Nitrogen-broadened halfwidths of HF lines in the 1-0 band

Nitrogen-broadened halfwidths for seven lines in the fundamental infrared band of HF have been determined from laboratory measurements at room temperature. The spectra were recorded using a Fourier transform spectrometer with a nominal resolution of 0.0603 cm^?1. A nonlinear least-squares spectral-fitting technique was used in the data analysis to obtain halfwidth values for the P3 through R3 lines, with an average uncertainty of approximately 15%.
