Notes:
The Rotating-Rod Model is modified to make the adjustable α parameter which appears in the treatment energy dependent. Its predictions for opacity and excitation functions compare well with quasi-classical H3 trajectory results, for translational and vibrationalenergy variations and isotopic mass effects. The Frozen-Orientation Model in its present form is incapable of such an agreement for mass combinations other than H + D2. It is suggested that the decreaseof α with energy can be interpreted as a transition from adiabatic tosudden behavior, where alignment is only on the average, and much energy isdeposited in the bending modes. This is supported by a correlation between α and the average final rotation.
