Π State

Spectra due to the A2Σ+–X2Π transition of the hydroxyl radical in electric fields of over 300 000 V per cm have been obtained. The dipole moment of the A2Σ+ ν = 0 state of OH has been determined to be (1.98 ± 0.08) D. From the variation of the dipole moment with vibrational quantum number in the 2Π state, the transition probability for the pure vibrational transition ν = 1 →ν = 0 has been estimated to be A10 = 80s−1.

Transition Energies

Variational ro–vibrational wave functions are calculated using an Eckart?Watson Hamiltonian, which has embedded an ab initio potential energy function. These wave functions,together with an ab initio dipole moment function,are employed to predict transition energies and absorption intensities. The radiative transition probability integrals are determined using a novel adaptation of the Harris–Engerholm–Gwinn integration scheme. The method and solution algorithm yields results in excellent agreement with previously determined experimental and theoretical electric dipole allowed transitions for the 1 A 1 ground state of H 2 O. The method has also been applied to the 1 A 1 states of the helide analogs of water, namely He 2 O 2+ and He 2 S 2+, in order to predict their ro–vibrational transition energies and absorption intensities, thereby facilitating their possible interstellar detection.

Intensity Measurements

Photoelectric intensity measurements in emission have been made at medium and high resolution on the CN violet system which was excited in the active nitrogen-carbon tetrachloride afterglow. Line and band intensity profiles have been interpreted in terms of transition probability parameters through comparison with realistic computer-synthesized spectra.

The energy states for the J , b , ɤ bands and electromagnetic transitions B (E2) values for even – even molybdenum 90 – 94 Mo nuclei are calculated in the present work of "the interacting boson model (IBM-1)" . The parameters of the equation of IBM-1 Hamiltonian are determined which yield the best excellent suit the experimental energy states . The positive parity of energy states are obtained by using IBS1. for program for even 90 – 94 Mo isotopes with bosons number 5 , 4 and 5 respectively. The" reduced transition probability B(E2)" of these neuclei are calculated and compared with the experimental data . The ratio of the excitation energies of the 41+ to 21+ states ( R4/2) are also calculated . The calculated and experimental (R4/2) values showed that the 90 – 94 Mo nuclei have the vibrational dynamical symmetry U(5). Good agreement was found from comparison between the calculated energy states and electric quadruple probabilities B(E2) transition of the 90–94Mo isotopes with the experimental data .
