摘要：

Pressure effects, broadening and shift, on H20 due to air were measured precisely for 271 rovibrational lines in the ν2 band by using a Fourier transform spectrometer. Rotational dependences of these effects were clearly observed in the present study which includes high-J transitions up to J 18 ← 17. The observed rotational dependence is pronounced. Very small pressure-broadening coefficients were obtained for high-J transitions, e.g., 0.011 cm-1/bar for the unresolved K-doublet, 180,18 ← 171,17 and 181,18 ← 170,17, whereas medium-J transitions exhibit larger broadening, i.e.,74,4 ← 63,3 yields 0.087 cm-1/bar. © 1993 Academic Press, Inc.
