Application Notes & Pulse Sequences
General Overview
We welcome submissions from users.
The ZIP archives below contain the application note in Adobe pdf file format and the TNMR data file and pulse sequence.
For single resonance systems, e.g. (Apollo/Discovery HF1/LF1) download the single resonance ZIP archive where specified.
Tecmag users with multiple resonance systems, e.g. (Apollo/Discovery HF2/HF3/HF4) must download the ZIP archive for multiple resonance spectrometers.
Warning!!! DO NOT DOWNLOAD THESE SEQUENCES UNLESS YOU HAVE AT LEAST VERSION 2.0 OF NTNMR. Check the version of NTNMR by going to the Help|About menu. To update an older version of NTNMR, please contact Tecmag's support group
Pulse Sequences
- APT
The Attached Proton Test (APT) experiment produces 13C-decoupled spectra with C-H multiplicity discrimination.

- COSY (Magnitude)
The COSY pulse sequence generates a 2D NMR spectrum that correlates homonuclear-coupled nuclei. The basic COSY technique with phase cycling for magnitude processing, 2D NMR data acquisition setup and processing on Tecmag spectrometers is described. An NMRscript is provided for 2D magnitude data processing.

- COSY (Phase Sensitive -- States)
The basic procedure of 2D States (also called States-Haberkorn-Ruben, RuSH, or Hypercomplex) phase sensitive NMR data acquisition and processing on Tecmag spectrometers is described. An NMRscript is included for 2D States data processing.

- COSY (Phase Sensitive -- TPPI)
This experiment incorporates the Time-Proportional receiver Phase Incrementation (TPPI) technique in the COSY pulse sequence to yield a pure absorption phase 2D spectrum. The basic procedure of 2D TPPI phase sensitive NMR data acquisition and processing on Tecmag spectrometers is described. An NMRscript for the TPPI 2D data processing is provided.
