 Title: INTERNUCLEAR POTENTIAL AND EQUILIBRIUM STRUCTURE OF $N_{2}O$ Creators: Teffo, J.- L.; Chedin, A. Issue Date: 1989 Abstract: The internuclear potential up to sextic terms and the equilibrium structure of nitrous oxide molecule are reinvestigated using the algebraized contact transformation method previously applied to carbon dioxide. Infrared spectroscopic data for a large number of vibrational levels belonging to six isotopic species of $N_{2}O$ are included in the refinement. The following R.M.S. between calculated and experimental molecular constants are obtained ($cm^{-1}$)$\begin{array}{llc} CONSTANTS &NUMBER& R.M.S\\G_{v}&267&0.047\\B_{v}&319 &2.16 \times 10^{-5}\\D_{v} &333 &5.64\times 10.^{-9}\end{array}$ The equilibrium bond lengths are found to be (A) $r_{MM} = 1.127292(37) r_{MO} = 1.185089(37)$ from which accurate values of equlibrium and ground state rotational constants are calculated for the 12 isotopic species of $N_{2}O.$ URI: http://hdl.handle.net/1811/17888 Other Identifiers: 1989-RE-4
