描述From the beginnings of modern chemistry, molecular structurehas been a lively area of research and speculation. For more than halfa century spectroscopy and other methods have been available tocharacterize the structures and shapes of molecules, particularlythose that are rigid. However, most molecules are at least to somedegree non-rigid and this non-rigidity plays an important role in suchdiverse areas as biological activity, energy transfer, and chemicalreactivity. In addition, the large-amplitude vibrations present innon-rigid molecules give rise to unusual low-energy vibrational levelpatterns which have a dramatic effect on the thermodynamic propertiesof these systems. Only in recent years has a coherent picture of theenergetics and dynamics of the conformational changes inherent innon-rigid (and semi-rigid) molecules begun to emerge. Advances havebeen made in a number of different experimental areas: vibrational(infrared and Raman) spectroscopy, rotational (microwave)spectroscopy, electron diffraction, and, most recently, lasertechniques probing both the ground and excited electronic states.Theoretically, the proliferation of powerful computers coupled withscientific insight

Vibrational Potential Energy Surfaces of Non-Rigid Molecules in Ground and Excited Electronic States cm. for the S.(n,π.) electronic excited state. The vibrational frequencies for the three carbonyl motions and the nine ring modes were observed for the excited state. Bands at 67, 158, and 256 cm. for the d. species, at 63, 147, and 240 cm. for the 5-d., isotopomer, and at 59, 138, and 227 cm. for

Jaan Laaneomagnetic phenomena contribute but at that time there were not sufficient data to fully conclude on the nature of parity operation in weak interactions [1]. For atomic transitions, the fundamental interaction is of electromagnetic origin and the experimental confirmation of parity conservation in at

R. D. Browne as the nonrenormalizab- ity problem present in the old V–A theory of weak interactions on the road to the standard model. An extension beyond the standard model can easily be ruled out as witnessed in the case of technicolor. However, a consistent framework with supersymmetry for a resolution of t
