Solvent and Temperature Dependence of the Hyperfine Coupling Constants in CTPO

摘要

The hyperfine coupling constant to the proton in the 4 position of the nitroxidespin label 4-protio-3-carbamoyl-2,2,5,5-tetraperdeuteromethyl-3-pyrroline-l-yloxv (mHCTPO) has been measured in seven solvents of varying polarities at 259 and 323 K. All of the proton hyperfine coupling constants in 3-carbamoyl-2,2,5,5,-
