For the "shotgun" approach, saliva samples ($\pu{1 mL}$) were pre-fractionated with the use of Millipore ultracentrifuge filters (Millipore Corp., Billerica, MA, USA). Individual fractions were treated with $\pu{10 mM}$ dithreitol for $\pu{30 min}$, and then $\pu{50 mM}$ iodoacetamide for $\pu{30 min}$. This reaction sequence in Ref.1 has a clear intention: ...

Potentiology is a field that began in the early days of quantum mechanics: 1924: John Lennard-Jones publishes the Lennard-Jones pontial 1929: Philip M. Morse publishes the Morse potenital. The most recent reference you gave was a potential from: 1940: by Hugh Hulburt and Joseph Hirschfelder You seem to be hoping that in the last 80 years, someone might ...

The problem with computational chemistry software (ORCA, GAMESS etc.), as described in NotEvans' answer and in various comments, is that they only spit out a list of chemical shifts and coupling constants. For example, this is part of a typical ORCA output: -------------- Nucleus 34H : -------------- [...] Total shielding tensor (ppm): 28....
