 Title: Assignment of the $\nu_{1}+\nu_{2}$ and $\nu_{2}+\nu_{3}$ bands of the high resolution $^{14}NH_{3}$ FTS absorption spectra Creators: Guelachvili, G.; Rao, K. Narahari; Tu, N. Issue Date: 1987 Abstract: The Fourier transform absoption spectra of $NH_{3}$ with a resolution of $0.005 cm^{-1}$ were recorded at Laboratoire D'Infrarouge of Universite de Paris-Sud. The assignment of the $\nu_{1}+\nu_{2}$ and $\nu_{2}+\nu_{3}$ bands of $NH_{3}$ has been carried out for the J value as high as 13. The inversion-rotational energy levels of the ground states of $^{14}NH_{3}$ has been calculated. These energy levels are compared with the best previous $work^{(1)}$ which shows an agreement within $0.001 cm^{-1}$. URI: http://hdl.handle.net/1811/17263 Other Identifiers: 1987-RB-9
