“…Under the same experimental conditions, no continuous emission was observed under the lines of the b -+ X bands (upper limit I 1% of the intensity of the discrete lines). Weak continua were observed under the lines of the 0-0 and 0-1 bands of the ulAK + X 3 2 ; system, confirming the results of a previous low-resolution study [28]. Measurements of the b -+ u band at low pressure and low resolution (10 cm-') showed that the form of the continuum is identical to that of the unresolved band.…”

“…According to this hypothesis, the relative efficiencies of different collision partners in inducing the b --f a and a + X transitions of 0 2 should go in parallel. Hitherto, accurate rate constants for collision-induced emission of the a + X transition have been measured only for Oz and NO as collision partners [28,29]. However, preliminary measurements have shown that the rare gases Ar and Kr as well as NZ, SF,, SOz, and PC13 are much less efficient than is Oz in inducing a + X emission (kc 5 cm3 s-l [29])*.…”

“…Recently, collision-induced emission of OZ(a):O2 and 02(a):N0 complexes has been observed in the 0-0 and 0-1 bands of the a + X transition, and rate constants for the collisional processes have been measured [28,29]. The 0-0 band of the b'X.,f -+ alAg transition at 1.91 pm was first observed at low spectral resolution by Noxon [30].…”

In flow tube studies of the quenching of 0 2 ( b ' Z i ) , broad band emission of Oz(b):M collision complexes was found to appear under the discrete rotational lines of the 0-0 band of the b'Cb -+ a'A, electric quadrupole transition at higher oxygen pressures and on addition of foreign gases. Bimolecular rate constants for the collision-induced emission processes have been derived from the ratio of the intensities of the discrete lines and the continuum as well as from lowresolution measurements of the relative intensities of the b + a and b + X bands as a function of 0 2 and added gas pressure. They range from S l O -" cm3 s-' for He to =4 X cm3 s-' for Pc13 vapor.

“…Several other less direct measurements of the rate coefficient agree with the recommendation, including Clark and Wayne [270], Findlay et al [453], and McLaren et al [894]. Wildt et al [1456] report observations of weak emissions in the near IR due to collision-induced radiation. Wildt et al [1457] give rate coefficients for this process.…”
