What's new in 2004
August 10, 2004:
The installation of Java plug-in for Internet Explorer 5.X and 6.0 in Windows operating system is described for running applets compiled with Sun's J2SE v1.2 SDK or higher. This installation is required for Windows XP which does not contain Microsoft Java Virtual Machine.
May 17, 2004:
Amplitude-modulated and phase-modulated shifted-echo pulse programs for Avance NMR spectrometers and 3Q-MAS experiments are provided by Redouane Hajjar.
May 1, 2004:
The various MQMAS sequences applied to half-integer quadrupole spins and the associated references are presented in Home and Applets > Pulse Sequence > MQMAS pages.
For each sequence, practical data are provided: pulse-sequence diagram, coherence-transfer pathways, detection mode in F1 dimension ...
The symbols (1), (2), (3), or (4) at the end of a reference title mean the pulse-sequence diagram, the coherence-transfer pathways, the phase-cyclings, or the receiver phase relationship are available in the reference.
March 1, 2004:
The procedure for shearing a 2D MQMAS spectrum of half-integer quadrupolar spin with the processing software RMN(fat) of P. J. Grandinetti is provided by Yannick Millot in the Pulse program page.
February 1, 2004:
The installation of Mozilla 1.6, Java 2 Runtime Environment, and Java plug-in for Red Hat Linux 8 is described in the FAQ page.
January 24, 2004:
The other NMR applets for a single crystal and for a powder written for SUN's JDK1.1.8 are available from the HOME page. The associated applet source codes are also available for downloading.
January 5, 2004:
Four applets (one-pulse and MQ-MAS for a single crystal and for a powder) written for SUN's JDK1.1.8 are included. From user point of view, the main improvement of these applets is the simultaneous displacement of the pulse length with the corresponding simulated line intensity using a single scrollbar.
Unfortunately, the number of pulse length is limited to about 100. Therefore, the line intensity simulation must be performed in several steps if the number of pulse length is greater than 100.
The applet source codes of the NMR one-pulse sequence applied to a single crystal, written for SUN's JDK 1.1.8, are available for downloading. The installation instructions are provided for WINDOWS-based computer users. They are similar to those written previously for SUN's JDK1.0.2. The applet source codes of the other NMR pulse sequences will be available for downloading soon.
The main changes in the new source codes concern with the event handling. Each event appears as an anonymous class inside OneXtalJDK118.java. As a result, more files are generated by the compiler. They have the following filenames: OneXtalJDK118$i.class, where i is an integer.
The JDK1.1.8 applet source codes describing the one-pulse sequence for a powder and the MQMAS sequences for a single crystal and for a powder are also provided.
