We present, for WINDOWS-based computers, simplified instructions to install and to run the source codes of the two-pulse nutation NMR applet for a single crystal. 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 JDK if you don't have it already.

Step 1: Install folders

(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 TwoPulseXtal. The MANIFEST.MF and TwoPulseXtalJDK118.jar files that support the applet will be saved in the TwoPulseXtal folder.

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

Step 3: Compile *.java files

(1) We open a DOS window.

(2) We set path to include JDK10's bin, which is the directory of Java compiler (javac):

C:\Users\pm@pascal-man.com> path C:\java10\bin; %path%

(3) We change the directory to that of TwoPulseXtal:

C:\Users\pm@pascal-man.com> cd C:\nmr-applet\TwoPulseXtal

(4) We compile all the *.java files contained in the ppmrmn folder:

C:\nmr-applet\TwoPulseXtal>javac ppmrmn\*.java

(5) We create a MANIFEST.MF file in the TwoPulseXtal folder:

C:\nmr-applet\TwoPulseXtal>echo Main-Class: ppmrmn.TwoPulseXtalJDK118 > MANIFEST.MF

(6) We create an executable jar file, TwoPulseXtalJDK118.jar, in the TwoPulseXtal folder:

C:\nmr-applet\TwoPulseXtal>jar cvfe TwoPulseXtalJDK118.jar ppmrmn.TwoPulseXtalJDK118 ppmrmn

(7) We execute the jar file:

C:\nmr-applet\TwoPulseXtal>java -jar TwoPulseXtalJDK118.jar
