Abstract
In continuation of our $analysis^{1, 2}$ of the antisymmetric wagging band $(v_{a} = 1 \leftrightarrow 0$, 1020--860 $cm^{-1}$) of hydrazine, $NH_{2}NH_{2}$, an examination with $0.002 cm^{-1}$ resolution has recently been made by the use of infrared diode lasers. The J-structures of the $a-^{R}Q_{5}, b-^{R}Q_{5}, b-^{P}Q_{8}, b-^{P}Q_{9}, c-^{R}Q_{3}, c-^{P}Q_{8}, d-^{R}Q_{7}, d-^{R}Q_{5}, d-^{P}Q_{7}$, and $d-^{P}Q_{8}$ clusters have been analyzed, where a, b, c, and d are the components of the inversion splitting in each transition (C-type) (see the figure). It has been found that the inversion splitting becomes smaller with increasing J and with increasing K, both in the $v_{a}=0$ state (shown by b-c) and $v_{a}=1$ state (shown by a-d). An explanation is given for this finding. [FIGURE]
