Instructions for installing and running the source codes of Hahn echo nutation NMR applet for powder

Home and Applets > Download JDK1.0.2 Applet Source Code > Hahn Echo for Powder

We present, for WINDOWS-based computers, simplified instructions to install and to run the source codes of the Hahn echo nutation NMR applet for a powder. We should read the detailed instructions given about the source codes of the one-pulse nutation NMR applet for a single crystal before starting.

Download JDK1.0.2 (3.8 Mb exe file)
and API doc (750 kb zip file) if not yet.

Step 1: Install folders

IMAGE of the nmr-applet folder

(1) We create, if not yet, a folder called nmr-applet in our hard disk c.

(2) In the nmr-applet folder, we create another folder called HahnEkoPowder. The applet.html file (see Step 4) that supports the applet will be saved in the HahnEkoPowder folder.

(3) In the HahnEkoPowder folder, we create the ppmrmn folder, whose name must not be changed, because ppmrmn is involved in the Java files as a package.

Step 2: Download *.java files

We download the following six Java files into the ppmrmn folder created in Step 1 by clicking on their links. (52 Kb) (7 Kb) (2 Kb) (3 Kb) (2 Kb) (2 Kb)

Step 3: Compile *.java files

We open a DOS window. Then we select, copy, and paste the following green line(s) after the prompt (c:\windows>) to compile *.java files:

c:\jdk1.0.2\bin\javac c:\nmr-applet\HahnEkoPowder\ppmrmn\*.java

Step 4: Edit and run applet.html

(1) We select, copy, and paste the following green lines in a file of MS Bloc-notes.

<!doctype html public "-//w3c//dtd html 4.0 transitional//en">
  <title>Nutation NMR applet for Hahn echo sequence applied to a powder</title>
  codebase = "."
  code = "ppmrmn.HahnEkoPowder.class"
  name = "NMR-Applet"
  width = "700"
  height = "390"
  hspace = "0"
  vspace = "0"
  align = "top"
>Applet for calculating and fitting the powder NMR line intensity of quadrupole spin excited by the Hahn echo sequence.</applet>

(2) We save the file as applet.html in the HahnEkoPowder folder (See the image of Step 1).

(3) Clicking the icon of the applet.html file in the HahnEkoPowder folder will start the applet in the web browser.

A page of our web site describes the operation of this applet.
