35Cl nuclear quadrupole resonance of the N—Cl bond

Abstract

The ³⁵Cl n.q.r. frequencies of seven N-chloro molecules are reported and with those of five additional molecules in the literature, interpreted using BEEM and BEEM-π. The frequency is dependent on the hybridization of the N atom: with tr¹tr¹tr¹π² hybridized N the ³⁵Cl frequency is around 55 MHz, with tr¹tr¹tr²π¹hybridized N around 46 MHz and with te¹te¹te¹te² hybridized N at 44 MHz.
