## Abstract The ^11^B and ^2^H spinโlattice relaxation times, __T~1~__, were measured for sodium cyanoborohydride (BH~3~CN^โ^) and sodium cyanoborodeuteride (BD~3~CN^โ^) in methanolโethylene glycol solution as a function of temperature. Both ^11^B and ^2^H __T__~1~ minima were observed, yielding ^1

โฆ Synopsis
SCF MO CIICUIXIO~S at the 6.31G** level of approumauon are reporred for 'H and "N eleclrx licld gradients III HCN--HCN. HCN-HF, and CH3CN.m.HF dlmers, wth emphasis on the configurational dependence oi these quantitxs in (HCN),. In compxaon wth available experimental nuclcm qu3drupolar coupling conslants, the calcularcd values for rhe monomers and drmers ckhlbit an accuracy of = 105, which is comparable lo that of other spectroscopic parameters. The unphcauons of hydrogen bondmg for quadrupolar spin-htticc rehution T;Ltes are bnefly discussed.
