Inversion-vibration and inversion-rotation interactions in the ammonia molecule
(Elsevier, 1962)
An attempt has been made to extend the theory of ammonia inversion in order to account for the dependence of the inversion splitting on the full set of vibrational and rotational quantum numbers. The potential energy of ...
Vibration-rotation energies of tetrahedral XY4 molecules : Part II. The fundamental [nu]3 of CH4
(Elsevier, 1961)
The matrix elements derived in the first paper of this series are used to compute the frequencies of the tetrahedral fine structure components of the rotational lines of the fundamental [nu]3 of CH4. The theoretically ...
The vibration-rotation energies of tetrahedral XY4 molecules : Part I. Theory of spherical top molecules
(Elsevier, 1961)
The theory of vibration-rotational perturbations in tetrahedral XY4 molecules has been reexamined in the light of the modern theory of angular momentum coupling. It is shown that, even to third order of approximation, the ...
Calculation of the absorption coefficient for lines with combined Doppler and Lorentz broadening
(Elsevier, 1965)
Methods are described for calculating the spectral absorption coefficient for lines with combined Doppler and Lorentz broadening.
Ultimate sensitivity and practical performance of the tellurium photoconductive detector*
(Elsevier, 1961-03)
Calculations of the ultimate sensitivity and measurements of the practical performance have been made for the tellurium photoconductive detector. For the condition that detector sensitivity is limited by fluctuations of ...
Electric field induced spectra of molecular hydrogen, deuterium and deuterium hydride
(Elsevier, 1968-09-18)
The electric field induced spectra of molecular hydrogen, deuterium and deuterium hydride was observed in the pressure range of 0 to 600 psi. Thirteen lines each of the fundamental vibration-rotation band were observed for ...
