摘要：
The line mixing effect for two pairs of transitions with rotational quantum numbers (3 1 2) <- (4 1 3), (3 2 1) <- (4 2 2), (4 3 1) <- (3 3 0) and (4 2 2) <- (3 2 1) in the nu(1) + nu(2) + nu(3) band of H2O has been studied. The measurements were performed at room temperature, at the spectral resolution of 0.01 cm(-1) and in a wide pressure range of helium. Pressure-broadening and -shifting coefficients and mixing parameter were obtained with help of the line profile using the Rosenkranz first-order approximation.
