We have designed and constructed a novel gas cell for infrared spectroscopic studies. Detailed features of the cell are described. Gas-phase spectra have been obtained for N-methylacetamide, camphorolactam, and acetyl-L-alanine-N-methylamide at elevated temperatures and high vacuum. The results show highly resolved spectra for cis and trans amide bonds.
