摘要：

The temperature dependence of the N-14 NQR frequencies have been measured in a series of thermochromic and photochromic salicylideneanilines and related compounds using nuclear quadrupole double resonance. The results show that, in agreement with previous measurements, there is a fast exchange between inequivalent sites in the O-H ... N bond. The energy difference DELTA-E of the two proton sites was calculated for all the compounds and shows that it depends on their thermochromic behavior which is connected with the structure of the compounds.
