Strong vibrational coupling between the P O(H) stretching and POH out-of-plane bending modes is observed. Ethylene diammonium groups are crystallographically different in the unit cell.doi:10.1016/0022-4596(89)90069-8Daizy PhilipG. Aruldhas

New vibrational structure is resolved for both neutral species, especially activity of the ν 5 hydrogen umbrella modes. The ν 6 out-of-plane bending mode fundamental frequency is measured for the first time in both systems and found to be 420(10) cm 1 for CH 2 CN and 389(8) cm 1 ...

For multiplicity distribution measurements, in order for tracks to remain within the acceptance of the SPD in the η versus zvtx plane, the following requirements were imposed on the vertex position along the z axis: |zvtx| < 10, 5.5 and 1.5 cm for |η| < 0.5, 1 and 1.5, respectively...
The results are in excellent general agreement with experiment: the ground state of CH2 is a linear 3Σg- state, whose potential energy curve crosses that of the lowest singlet state which is bent. The CH3 radical is predicted to resist out-of-plane deformation quite strongly, and the ...
A bending movement that decreases the angle of the joint and brings the articulating bones closer together. Extension The reverse of flexion, involving movement that increases the angle between the articulating bones. Abduction Movement of a limb away from the body midline in the frontal plane. ...
