Carbon-13 T1 study of aldehydes and aldehyde oximes
Abstract
The 13C spin lattice (T1) parameters for some aldehydes and their oxime derivatives have been examined and interpreted in terms of self association and segmental motion. The strength of the hydrogen bonding in the oximes was examined by a temperature-dependence study of T1. Some evidence was found to support an earlier proposal that the E(anti) isomer participates less effectively in hydrogen bonding than the Z(syn) isomer.
