The rotational spectrum of a hydrogen-bonded dimer between vinylacetylene (H,C=CHC=CH) and HF has been obtained with a pulsed-nozzle Fourier-transform mxrowave spectrometer. Analysis of the derived spectroscopic constants shows that the HF molecule attaches preferentially to the triple bond in viny

SCE' wavefunctions with similar extended Gaussian bases for the series HCOX with X = H, OH ( s y n and a n t i ) , NHz, CN, and F yield closely similar charge deformation density maps in the formyl region of all six molecules. The differences, measured by moments of partitioned atomic deformation de
The mass spectra of a series of mefa-and para-substituted phenyl acetates have been examined. Substituent effects have been correlated with A(AP-IP) values and by using the Harrison and Chin approach. The bond-cleavage and rearrangement reactions of phenyl acetates are compared with the correspondin
