The Topspin software on 500-3 has been upgraded from version 4.2.0 to 4.4.1. This post illustrates notable changes, including automatic queuing, the new “apbk” autophase/baseline button, and new aspects of the interface. Expect 600-1 to be upgraded like this soon.
Many chemical structure questions can be answered with 1H-1H distance estimates derived from the 1D NOESY experiment. There are a variety of ways to set up this experiment, but we now have two short videos that UChicago users can access with their phones at the spectrometer – no homework or special prep required.
Tweaks have been made to all default 1H and 13C 1D and 2D experiment parameter sets so they have been tested as effective and are the same on all spectrometers. If you have a 10mg properly-prepared sample, you are assured of getting good data using default parameters with these experiments no matter which instrument you use.
500-1 is open, supporting walkup experiments in Searle. It’s outfitted with a different probe to provide better 13C sensitivity and capabilities of observing 31P, 11B, 195Pt, and more. Spectra are shown for a standard 10 mg/mL sample of carvone to provide a visual basis for comparison.
Major events took place in Week 1 of reopening, including a number of hardware and software upgrades to NMR systems. For Week 2, expect to continue using 400-1 for routine work. Other systems are actively being configured and upgraded in various ways, so please be patient.
