✦ Synopsis

We also wish to celebrate, on this occasion, the '60th anniversary' of the work of Pfau and Plutfner on the correct structure of azulenes which appeared in this journal [la].

)) According to the CSD, only one X-ray crystal structure of a benzazulene, namely that of 10-(methylamino)benzlflazulene, has been determined [6].

The course of the intercalation and deintercalation of water molecules in vanadyl arsenate has been studied by X-ray diffraction analysis and by infrared and Raman spectroscopies. The formation of VOAsO 4 hydrates at ambient temperature has been found to depend on relative humidity (r.h.): VOAsO 4 ⋅

A dipeptide taste ligand L-aspartyl-D-2-aminobutyric acid-(S)-alpha-ethylbenzylamide was found to be about 2000 times more potent than sucrose. To investigate the molecular basis of its potent sweet taste, we carried out conformational analysis of this molecular and several related analogues by NMR
