Question
Users of this program can employ DAISY to simulate spectra and aid in multiplet analysis. For 10 points each:
[10h] Name this program similar to Mnova, whose version 4.3 was released in August 2023. This program uses commands such as “apk” (“A-P-K”) and “abs” (“A-B-S”) to perform automatic phase and baseline corrections.
ANSWER: TopSpin
[10m] Instruments that use TopSpin can deploy a zgpr pulse sequence to perform the “presaturation” method of this task. The “jump and return” method can be used for this task on substances like deuterated chloroform.
ANSWER: solvent suppression in NMR [accept any answer suggesting that the peaks or signals from the solvent are removed; prompt on any answer like cleaning up NMR signal, removing noise in NMR, refining NMR signal, refining NMR spectrum, or calibrating NMR; prompt on NMR by asking “what specific aspect of obtaining an NMR spectrum?”; prompt on suppression]
[10e] The first step of NMR data analysis is to perform this operation on the free induction decay signal in the time domain to give the chemical shift in the frequency domain.
ANSWER: Fourier transform [prompt on FT]
