The N–H link as a ‘probe’ for the electronic structure of the phosphorus–nitrogen bond in aminophosphines. An infrared spectroscopic study
Abstract
Mechanical anharmonicity and hydrogen bond donor ability of the NH group in 26 aminophosphines X2P–NHR have been measured; large variations have been observed, which are related to the effect of substituents X on the s character of the nitrogen part of the NH bond orbital.
