There are a few embedded pdf documents added below in this web page. In certain systems these embedded pdf does not appear, since the html code does not work. In such events, there is a hotlink for the embedded pdf included on top of each embedded document, from which the pdf document can be downloaded and saved to the resident disk. For any clarifications required or for sending FEEDBACK info the email form (on the left-hand-side column) may be filled and submitted. Find this also displayed at the Web Page: https://saravamudhan.tripod.com/biodata.html#CURRENT The emphasis in the above file is the simplicity of handling the Commutation Principle and Properties with Spin Hamiltonians and Spin Functions and Classical vectors for angular momentum and associated magnetic moments. The Spin orbit coupling requires a better understanding of coupling of angular momenta and the Commutation criteria of the resulting angular momenta associated with magnetic moments. Suggested Reference: Chapter 8; Angular Momentum in Quantum Mechanics in the book entitled: "QUANTUM CHEMISTRY" by Walter Kauzmann and the references list at the end of the Chapter. |

The URL links are hotlinks . click on the URL would display the webpage. Use the mouse 'right-click' and choose to open in new Tab/Window Before getting into the realms of Classical and Non-classical Vectors as described in documents below, it may be mentioned in terms of prerequisites that the subject matter becomes more tangible with hands on experience in Computing for the context of computational quantum chemistry. "GAUSSIAN" software is described in the pdf document Exploring-Chemistry-With-Electronic-Structure-Methods.pdf. This book is a study guide book for using "Gaussian 94" and the access to a Computational Engine with installed Gaussian software as ready to use along with a study guide book can be found in the well maintained on-line computational chemistry website http://www.webmo.net The website posting contains several computational chemistry engines along with Gaussian software. This Website contains a course outline for Computational chemistry and a well illustrated tutorial lessons. The constraint (mainly because it is free of cost) is that the jobs submitted should be completed within 1 minute for being "successful", other wise a "failed" in red message would be due at the end of 1 minute CPU time. A lot of experience is possible within this constraint and when this constraint is an impediment alternative methods of acquiring the software are available as suggestions. Another Computational Chemistry software for beginners at the elementary level exposure to such uses of software package is ARGUSLAB. Read about this software and instructions to downlaod free and install in resident disc (unlike the online features) at this link: https://saravamudhan.tripod.com/arguslab-download-resources.pdf |

For what can be read in last line of pdf-embed above "What cannot be shown in the Vector diagram"----> an alternative?
NON-CLASSICAL VECTOR DIAGRAMS
The Product Operator Formalisms are based on Density matrix and Density operators. And, the time evolutions are described by the unitary operators defined appropriately for specific interactions / interaction parameters. The beginners usually require a break through with the operator formalisms and the operator algebra to further follow the density matrix time dependences before and after transforming by the operators. It may be necessary to distinguish the evolutions during the pulse periods (under perturbations) and after the pulse had its effect on the spin system, it may be termed as Free Evolution of the spin system from that time onwards. In particular for students with chemistry background, who can be better with such effects describing them with a vector-representation as they are familiar with classical vectors?
When it is a question of handling the two spin system certain aspects becomes difficult to explain from classical vectors point of view. Even with a non vanishing coupling (Spin-Spin J coupling) when the two spins are ranging from an AX system through AB to A2 type, explaining why the lines are not spilt in the case of equivalent nuclei (A2 case) while J coupling value is the same as in a AX case. Let alone the more complicated spin system cases. This is a case when the Higher order perturbation terms become important than the simple first order case. An effort is made in the presentation files to elaborate upon this complication. If one ventures into quantum mechanical terms, the explanation becomes simpler. However, it seems better to get an appreciation of this difficulty and the necessity for the quantum mechanical descriptions.
When from simple coherences in spin system ensembles, if one tries to explain coherence transfers and population transfers, the classical vector descriptions become inadequate and hence either one has to be content with entirely mathematical treatment which might appear abstract and may remain so as multiple quantum coherences are to be discussed.
This aspect as illustrated in the two power point presentation files would convince about the complications and the necessity for non classical vector diagrams. http://www.ugc-inno-nehu.com/alolc-qm/Jcoupling-evolution-1.ppt http://www.ugc-inno-nehu.com/alolc-qm/Jcoupling-evolution-2.ppt

| After the consideration of the exclusive spin Hamiltonian and spin Eigen functions, when considering the general two level systems with orbital functions of particles, as in the case of RP Feynman's paper above, the distinction between particle velocity and the electrostatic (electromagnetic) field velocity have to be considered. This distinction of particles and fields is normally a matter of study in physics, but with the advances in QM methodolgy related to spectroscopic and spectroscopic transition properties, demands that current curriculum includes tis distinction as a point to highlight from the secondary level chemical sciences onward. To this context the following displayed pdf contents and the subsequent video are included in this page. |

In view of inculcating ability to obtaining useful materials from Internet Resources for healthy reading habits, particularly with courses like this on Quantum Mechanics/Quantum Chemistry it is necessary to suggest certain reading materials be provided to reorient to think along the ways of Modern Physics transcending from the approaches of classical physics. Below is an example for voluntary reading on "EXPLAINING".Natural Phenomena" https://www.ugc-inno-nehu.com/alolc-qm/QC-WK-3-4-20pc.jpg
which is an excerpt from the pages of the book by Walter Kauzmann on Quantum Chemistry
.
| From Bohr's circular orbits to Schroedinger's Orbital picture could be intriguing to describe; as to how it could become possible to reconcile with such a development (Slides 8 & 9 of the Video nsc20-gu). And, at the same time recognizing a pattern from a set of randomly distributed (shuffled points of a pattern?) points could be equally intriguing matter for children; and hence is a pattern recognition is a children's exercise. |

On the Right hand side find image consisting of excerpts [page # 224 & 225] from the book on Quantum Chemistry by Walter Kauzmann. This gives the description of how electron motions can be envisaged in a Hydrogenic s-orbital to reconcile with the charge cloud picture from the solutions of Hydrogen Atom Schroedinger's equation. This may be considered a stretching of the imagination from the above visulaization in the powerpoint presentation.
