Title:High-resolution, Rotationally-resolved Ftir Spectrum Of The 3300 Cm−1 Transition Of Astrophysically-relevant Hcn
Author(s):Palko, Jessica
Contributor(s):Dodson, Leah G; Howard, Thomas
Abstract:Hydrogen cyanide (HCN) is ubiquitous in the interstellar medium, especially in the dying carbon star IRC+10216, where its abundance and reactivity are of great astrophysical relevance. We have developed a safe, robust synthesis and storage procedure for pure HCN gas, which is necessary for carrying out further studies on the reactivity of HCN in the gas phase. We present the high-resolution, rotationally-resolved vibrational spectrum of gaseous HCN obtained with a Nicolet iS50 Fourier transform IR (FTIR) spectrometer. Line-by-line frequency and spectral intensity data from the HITRAN database were used to fit the experimental FTIR spectra for the \nub{3} ro-vibrational transition (C-H stretch at 3300 cm$^{-1}$) of HCN. We will describe the current state of knowledge for this transition and compare our findings with the HITRAN database.
