Abstract

A large number of spin-rovibronic levels of the upper electronic state of $NH_{2}$ have been excited with a single mode rhodamine 6G dye laser. Fluorescence spectra were obtained over a wide spectral range (12000-3700 cm-1) using a Fourier transform spectrometer. Levels of the bending vibration were observed from $v^{\prime\prime} = 4$ up to 10, showing the reordering of the K-structure at the barrier to linearity: their observed energies are in good agreement with the predictions of Jungen, Hallin and Merer1 , Duxbury and $Dixon^{2}$ and Peric, Peyerimhoff and $Buenker^{3}$. Numerous vibrational levels involving $n\nu_{1}$ and $2\nu_{3}$ were also detected and approximate anharmonic parameters have been deduced.
