Investigation of Formaldehyde+Hydrogen Fluoride Complex in Gas Phase by the Help of Ftir Spectroscopy and Computational Methods

Abstract

High resolution infrared absorption spectra of the H 2 CO HF complex and its monomers are recorded in gas phase in C O and C H regions by means of Bruker HR 125 spectrometer recorded at 0 05 cm -1 resolution Upon the complexation in the HF stretching band of complex asymmetrical shape was not observed due to weak interaction couplings between C O and C H stretching of the H 2 CO HF complex Additionally quantum chemical calculations are performed in mp2 6311 g 3df 3pd approximation and energetic geometrical and spectral parameters are calculated
