Conformational analysis of apparicine using 1H nuclear magnetic relaxation: application of transient nuclear Overhauser enhancements
Abstract
1 H N.m.r. relaxation in apparicine in [2H6]acetone solution has been studied. Spin–lattice relaxation times, and selected steady-state and transient nuclear Overhauser enhancements are reported. In conjunction with spin–spin coupling constants these results permit an assignment of the molecular conformation.
