EXSY (Exchange Spectroscopy, NMR)
What is EXSY? Abbreviation for EXchange SpectroscopY, a technique in NMR measurements. Another name for NOESY. The pulse sequences are identical to NOESY.[1,2] Since correlated signals also appear ...
What is DOI?
You have probably seen the above number written in the corner of a paper at least once. This is a code called DOI (Digital Object Identifier). What is DOI? A DOI is a code that corresponds to ...
heavy drug (deuterated drug)
A heavy drug is a drug labeled with deuterium (2H, D).[1] By replacing C-H bonds at metabolic sites in drug molecules with more stable C-D bonds, metabolism can be slowed down. This deuteration makes ...
Process Mass Intensity, PMI
Process Mass Intensity (PMI) is the total mass of material used to produce a product of a given mass, determined in units of mass of input material (e.g., kg) per mass of product (e.g., kg). The PMI ...
