There are links to URLs which are hosted at the "geocities.com". This yahoo webhosting service has been closed and any page saved in the "geocities" would not be retrievable now. However, the author has made the effort to make available these geocities pages in another webhosting service with different domain name. The file names and some of the directory names have been retained while reposting the material. These renewed postings have been listed at : http://aravamudhan-s.ucoz.com/webpages_list.html . Identify the 'html' file name in the list and possibly the materials can be retrieved as if from the geocities posting. added on 18th Aug. 2010

An audio file has been uploaded which may be heard [ 6 Mins ] using the audio feature below { Eine Kleine Nacht Musik--- W.A.Mozart }: NOTE: Down bleow at the bottom ofthis page a falsh movie has been dispalyed which has an automatically turned "ON" audio trcak which would start playing when this page is dispalyed with the media player is set up. For availing the audio feature immediately below, scroll down the page and set the 'sound off' to 'sound on' at the flash movie pane by clicking on that 'OFF' text.

Welcome to this web site!

Spend a while by displaying the web site: http://saravamudhan.tripod.com/ and navigating through the pages for the Web Building Features and for the subject of scientific study as documented by this author in those web Pages.Then proceed to read through the contents below. S.Aravamudhan

Find below a prpesentation file in Video Format, trying to explain in part the significance of the initiative in building this website. (When the page is loaded the video at the end of this page will play the audio tarck. Set it to off by clicking on 'sound off' button provided there.)

A Video Movie on PULSED FT NMR

Find below links for two downloadable files. The first one is an article on "NMR as a tool for Structure Determination" for College and University levels . The second one is an NMR movie of the ACD Labs demonstrating features of a NMR software product.

An elementary article on NMR by Aravamudhan,S

The nmr article as in the .pdf file above have also been posted in a separate web page which can be displayed at the URL: http://www.geocities.com/saravamudhan2002/nmr_article.html

An NMR Movie of ACD Labs

In the event of the "NMR Movie" file above is not downloadable from this link, click and display the "Demo Movies" page of the ACD Labs from the link below: (These lines inserted on Wednesday, January 02, 2005) http://www.acdlabs.com/download/movies/mov_spec.html

This is the home page.

The purpose of this webpage is to suggest for display and view a Web Page built by me for Science Documentation. This has been built with the "Tripod" Webbuilding features. If this kind of documentation finds an appeal, those who are inclined to use such tools of Information Technology for promoting Science Communication may try to take initiative using the interactive Web page add-ons built in above in this Web Page. ------------S.Aravamudhan.

The information for contacts and the present occupational particulars about Dr.S.Aravamudhan are available from the Web Page URL: http://geocities.com/amudhan20012000/Addresspage.html . The Web page built by Dr.S.Aravamudhan displayable at the URL: http://geocities.com/amudhan_nehu/nehu_link.html is an example illustrating how to use the Computer "Office Tools" softwares for generating Science Documentation materials as drawings and graphics. Further few [ 8 distinct URLs] Webpages are all viewable at one instance in one FRAMED Single-window-Webpage-display { http://geocities.com/amudhan_nehu/highlights.html }. These would inspire a beginner atleast in starting to make use of the Web tools for Science documentation. Also attend to the contents of the Web Page URL: http://geocities.com/amudhan_nehu/it_classroom_tools.html in which these tools have been found as potential classroom teaching utilities.

As it can be found from some of the "geocities" Web Pages linked herein, files of a variety of FORMATs ".doc",".ppt", ".xls" etc., can be uploaded in such a way that they can be given a link at this page so that by clicking on those links, the files can be downloaded. Such features would also be part of this Web Page eventually for illustartion.

The following five powerpoint animated presentation files illustrate the elementary aspects of the magnetic resonance phenomena for illustarting in a school/college level classrooms.

The Scientific content documented in these pages pertins to the topic of magnetic resonance, particularly the Nuclear Magnetic Resonance - N.M.R. Besides the interests in the Webpage building what can be interesting in this context is the phenomenon of induced fields arising at specific sites within the substance, when materials are placed in external magnetic fields. Such fields are induced due to the changes in electron circulations in atoms and molecules which, in turn, means that the magnetic susceptibilities of electron charge clouds and the corresponding magnetic moments which cause the magnetization of materials. these can be absorbing when considered from the point of view of interpreting NMR spectra.

Webpage building does not cost much money. In fact most of the Web page documentations cited here for illustration and built by this author are all utilizing the FREE Web hosting facilities available at "Tripod" of Lycos Network and the "Geocities" of the Yahoo. It is not too difficult to learn to access these web hosting facilities. It is mainly the initial breakthrough which has to be established to soon become independently capable of learning from the documented detailed instructions, most often with illustrations and examples.

specimen Movie file made with Windows Movie Maker: Down load and save it in resident disc to play with windows media player

A flash movie of about 3 mins 14 secs demo.This flash file is about 10MB size. And hence would take long time and require a larger bandwidth (A broadband internet connection) to load into the page.
