35Cl NQR of 11 Organic and 3 Inorganic Molecules

Abstract
The 35Cl NQR frequencies from 11 organic molecules and 3 inorganic molecules are given for 77°K. The frequencies are discussed in terms of σ and π inductive and conjugative effects of groups relative to the chlorine and compared to frequencies in analogous molecules. In [PCl4]+[BCl4], frequencies from both ions have been detected, and in [SCl3]+[SbCl6] the first frequencies to date from [SCl3]+ have been measured.
