Molecular dynamics simulations of the infrared spectrum of a generic simple polar diatomic in a liquid nonpolar solvent allow to reproduce the different prototypical experimental line shapes of this kind of systems. This is feasible by using different solute-solvent anisotropic potentials at fixed thermodynamic conditions. In the limit cases, the rotation of the diatomic is explained in terms o...
Bindra et al. @1# have recently reported on in-beam g-ray spectroscopic studies of Hg and on the observation of different band structures in this nucleus. In particular, they discuss the position of the well-known prolate band relative to the oblate ground-state band. They identified the 2 member of the prolate band and developed on this basis a discussion of the minimum in the prolate-oblate e...
High-spin states in 58Ni have been investigated by means of the fusion-evaporation reaction 28Si(32S, 2p)58Ni at 130 MeV beam energy. Discrete-energy levels are observed in 58Ni at record-breaking 42 MeV excitation energy and angular momenta in excess of 30h. The states form regular rotational bands with unprecedented high rotational frequencies. A comparison with configuration dependent cranke...
We analyse the excitation of 114 rotational transitions of vinyl cyanide (acrylonitrile), C 2 H 3 CN, in its ν 11 and ν 15 vibrational states, together with 98 transitions in the ground state. The data were taken from the SEST line survey of Sgr B2(N) in the 1.3 mm band. For the lines with energies above 200 K a rotational temperature of 440
wide compared with the length of the specimen, and so is the angle between the lateral edge of the kink band and the axis of extension, E = [sin xo/sin (xi + so) ] 1. (2) For narrow kink bands and deformation bands, (a) an approximate relation is s = cot (900 w); (b) a more precise relation where a and ,3 are the respective angles between the kink-band boundary and the active glide plane in the...
The changes that one observes upon the addition of CH3HgOH in the circular dichroism spec trum and ultraviolet absorbance spectrum of native calf thymus DNA, dissolved in buffered (pH 6.8) solutions of Na2S04 at pNa 2.0, 1.5, 1.0, and 0.0, respectively (pNa= —log [Na+]), are shown to be due to denaturation brought about by the organomercurial interacting with the base moieties of the polymer. ...
Observations of four comets made with the Far Ultraviolet Spectroscopic Explorer show the rotational envelope of the (0,0) band of the CO Hopfield-Birge system (C Σ– X Σ) at 1088 Å to consist of both “cold” and “hot” components, the “cold” component accounting for ∼75% of the flux and with a rotational temperature in the range 55–75 K. We identify the “hot” component as coming from the dissocia...
