Abstract
The method of laser‐excited vibrational fluorescence is used to measure the vibrational relaxation rates of NH3(ν2) in collisions with NH3, He, Ar, N2, and O2. The rates are found to be 3.8×10−11, 2.8×10−13, 1.8×10−13, 3.6×10−13, and 4.2×10−13 cm3 molecule−1 sec−1, respectively. Exciting to different rotational levels gives the same result within 10%.Keywords
