• quantification
  • A thermospray high-performance liquid chromatography-mass spectrometry method for the separation and quantification of tracer concentrations of isotopically labelled carbamazepine epoxide ([15N, 13C]CBZE) in the presence of steady-state levels of the anticonvulsant carbamazepine (CBZ) and its epoxide metabolite (CBZE) has been developed.

  • amide
  • This is illustrated for a backbone amide resonance in a sample of 15N-labeled human ubiquitin. (epfl.ch)
  • Using a synthetic macrocycle that enforces a two stranded parallel β-sheet conformation, we measured the lifetimes and frequency for six combinations of doubly 13C═18O labeled amide I modes using 2D IR spectroscopy. (wisc.edu)
