Instructions for installing and running JDK1.1.8 source codes of rotary-echo nutation NMR applet for powder




Home and Applets > Download JDK1.1.8 Applet Source Code > Rotary-Echo for Powder

We present, for WINDOWS-based computers, simplified instructions to install and to run the source codes of the rotary-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 JDK1.1.8 if you don't have it already.

Step 1: Install folders

IMAGE of the JDK1.1.8 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 RotaryPowder. The applet.html file (see Step 4) that supports the applet will be saved in the RotaryPowder folder.

(3) In the RotaryPowder 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 eight Java files into the ppmrmn folder created in Step 1 by clicking on their links.

RotaryPowderJDK118.java (45 Kb)
ComplexMat.java (7 Kb)
Population.java (3 Kb)
RealMat.java (2 Kb)
Graph.java (10 Kb)
Jacobi.java (3 Kb)
ListGentle.java (2 Kb)
Nmr.java (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:\jdk1.1.8\bin\javac c:\nmr-applet\RotaryPowder\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">
<html>
<head>
  <title>Nutation NMR applet for rotary-echo sequence applied to a powder</title>
</head>
<body>
<applet
  codebase = "."
  code = "ppmrmn.RotaryPowderJDK118.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 rotary-echo sequence.</applet>
</body>
</html>

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

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

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