Hydrogen is the most abundant molecule in the universe, and over the years has provided a fundamental testing ground for both theory and experiment. By symmetry, isolated H 2 molecules do not have allowed dipole rotational or vibration-rotational spe

The translation-rotation collision-induced spectra of N 2 –N 2 , O 2 –O 2 and N 2 –O 2 mixtures are calculated theoretically. For N 2 –N 2 , using the matrix elements for the quadrupole and hexadecapole moments and the isotropic and anisotrop

Herman–Wallis factors describing the effects of vibration–rotation interaction on the intensities of infrared and Raman spectra of diatomic molecules can be useful in analyzing spectroscopic data. Accurate analytic approximations based on the Dun

We obtain accurate analytical expressions for partition functions valid for all values of temperature by the application of the Euler—Maclaurin summation formula to that part of the sum over the energies that is dominant at high values of T. Severa

The emission spectrum from a low-pressure hydrogen chloride flame has been recorded in the 3.1–5.3 μm region at high resolution using a 4.5-m grating spectrometer coupled to a PDP-15 computer. The data obtained for the v → v - 1 band sequence, w

Rotational and vibration-rotational intensities (dipole-moment matrix elements and Einstein A coefficients) have been calculated for the four most abundant isotopes of CS for the following sets of rotational and vibrational quantum numbers: J ′ −

1. Shifts in the 1H and 31P-nmr signals originating from the outer and inner phosphorylcholine head-groups and from the lipid acyl chains are observed when phosphatidylcholine vesicles are treated with increasing extravesicular concentrations of the

Simple expressions for the expectation values of the kinetic and potential energies are derived for a Dunham oscillator. For low vibrational levels, these differ only slightly from results derived utilizing the semiclassical quantization condition, a
