Fourier transform infrared emission spectroscopy of the [6.7](2)Sigma(+)-X-2 Sigma(+) system of HfN

Research output: Contribution to journalArticlepeer-review

Abstract

The electronic emission spectrum of HfN has been observed in the near infrared using a Fourier transform spectrometer. HfN molecules were excited in a hafnium hollow cathode lamp operated with neon gas and a trace of nitrogen. The bands located near 5746, 5802, 6663, and 6715 cm(-1) have been assigned as the 0-1, 1-2, 0-0, and 1-1 bands of the [6.7](2) Sigma(+)-X-2 Sigma(+) transition. The rotational analysis of these bands has been performed and the equilibrium molecular constants for the lower electronic state of (HfN)-Hf-180 are omega(e) = 932.7164(15) cm(-1), omega(e)x(e) = 4.41299(65) cm(-1), B-e = 0.436217(18) cm(-1), alpha(e) = 0.002659(11) cm(-1), and r(e) = 1.724678(36) Angstrom. We believe that the lower state of this transition is the ground electronic state but more experimental and theoretical work is necessary to prove this. Our work represents the first experimental observation of an electronic transition of HfN. (C) 1997 Academic Press.
