Knowledge Base

Remote operation of Spectrometer (Windows Remote Desktop)

May 30, 2023Knowledge Baseacquisition, automation, remote

General Remote operation of the spectrometer gives you the same control you have when physically sitting at the spectrometer computer.  There is no need  to be logged in and have ICONNMR running prior to remote access as required for the… Read More

Structure Elucidation from 2D Spectra using Topspin CMCse module

February 7, 2023Knowledge Base2D, Analysis, Processing

The Structure Elucidation module in Topspin allows software assisted assignment of organic molecules using two dimensional COSY, HSCQ and HMBC spectra. A thorough description of all features of the module is beyond the scope of this knowledge-base entry. Links to… Read More

Remote operation of Spectrometer using VNC Viewer

January 6, 2023Knowledge Baseacquisition, automation, Offline, remote

General Remote operation of the spectrometer through VNC (Virtual Network Computing) gives you the same control you have when physically sitting at the spectrometer computer.  There is no need  to be logged in and have ICONNMR running prior to remote… Read More

ICONNMR Web Interface

December 16, 2022Knowledge Base, Uncategorizedautomation, Offline

When started, ICONNMR will automatically start a build in webserver. A running ICONNMR session can be accessed through a web browser A VNC connection can be established to give you direct access to the console Both methods require access to… Read More

Recovering from hangups of power glitches

June 16, 2022Knowledge BaseTroubleshooting

Topspin Window Locked, desktop responding If you are running automation, you may have timed out and were logged out of ICONNMR.  That will also lock certain functions in the main Topspin window.  Click on the [Change User] button on the… Read More

Converting spectral window to o1p and sw (and vice versa)

March 31, 2022Knowledge Baseacquisition

To translate a given sw and o1p to spectral limits, use leftlimit = o1p + sw/2 rightlimit = o1p – sw/2 For example, o1p = 6ppm and sw = 20ppm translates into a window of -4ppm to 16ppm. Converting a… Read More

Manualy Setting up 2D experiments

March 22, 2022Knowledge Base2D, acquisition

The procedure for running two dimensional spectra follows in general the procedure for one dimensional experiments with some modifications. Preparatory experiments It is recommended to always take a proton spectrum to verify sample purity, assess concentration and later use to… Read More

1D NOE Experiments

March 15, 2022Knowledge Baseacquisition, automation, NOE

The NOE (Nuclear Overhauser Effect)  experiment allows for the estimation of through space proton-proton distances. The two dimensional version will capture all possible pairs of protons, but can be lengthy and lack resolution. A one dimensional version of the experiment… Read More

NMR without deuterated Solvents

March 10, 2022Knowledge Baseacquisition

Deuterated solvent.typically used in NMR play several roles: Reducing Solvent signal, that otherwise may overwhelm sample signals internal calibration of ppm axis using shift of solvent signal Long term stability of field using deuterium Lock The topshim automatic shimming uses… Read More
