Optical absorption spectra of a few polyenes in the crystalline state have been studied. On adsorption of certain gases on the crystallite surfaces of polyenes. a new band appears on the low energy side of the long wavelength bands of these polyenes. The position of this band is 536,537 and 375 m,u

β¦ Synopsis
It is demonstrated that the inclusion of double-excited configurations in semi-cmpiricclf and B priuri calculations of polycnes leads to a significant alteration of the spectrum. In areement with the recent experiment of Hudson and liohlor, a forbidden ('A,) state appears below the strongly allmved ('I3,) state.

SCF-energy partitioning for three ternary intermolecular complexes, (HF)3, Li\*(OH2)2 and F-(H2 0)2, has been performed in order to obtain more information on the nature of the non-additivities in the energies of complexes. It is found that polarization forces dominate the three-body energies in the
Abstract The main problem facing patients with ulcerative colitis after mucosal proctectomy and ileo-anal anastomosis (MP + IAA) is severe frequency of bowel action. Although the addition of a pelvic reservoir can improve matters, some patients still complain of this problem. In an attempt to slow t
The influence of a hydroxyl group simulating Ser-48 in the hydride-transfer step characteristic of liver alcohol dehydrogenase is studied on the hydride-transfer reaction as modeled by a methanolate anion interacting with a cyclo propenyl cation. It is shown first that this is an adequate model by c
