Pressure broadening and shift coefficients have been measured for the
ν

ν
3 band of acetylene, C

2, D
2, air, and the noble gases at 295
K. Coefficients are reported for lines between 6470 and 6612
cm
−1 (1512–1546
nm). The pressure broadening coefficients are in general agreement with those reported for other vibrational bands, indicating that they are insensitive to vibrational excitation. The pressure shift coefficients, by contrast, are found to differ substantially among vibrational bands.
