“…Several experimental and computational studies on the kinetics of HCNO have been reported [16][17][18][19][20][21][22][23]. Despite the potential importance of O 3 , HNCO and HCNO we could not find neither experimental nor theoretical report on O 3 -HNCO or O 3 -HCNO interactions.…”

“…Our previous studies [2][3][4][5][6] show that HCNO is a highly reactive molecule. Many secondary reactions following the photolysis can therefore occur.…”

“…The rate of the rise is primarily determined by the rate of collisional relaxation of a nascent vibrational distribution to a Boltzmann distribution. The buffer gas (CF 4 or SF 6 ) [4,5] was used to maximize this relaxation rate. Our product yield measurements assume that the detected products have reached a…”

“…Reactions (2)-(6) have been studied previously in our lab [2][3][4][5][6], resulting in the following rate constants: k 2 = (5.32 ± 0.4) × 10 -12 cm 3 molecule -1 s -1 , k 3 = (1.04 ± 0.1) ×10 -10 cm 3 molecule -1 s -1 ,…”

“…HCNO (fulminic acid) is the less stable isomer of isocyanic acid; the kinetics of several reactions involving HCNO has only recently been studied [3][4][5][6][7]. There is only one previous study of the photochemistry of HCNO, an infrared laser spectroscopic study from our laboratory that identified five separate photolysis channels in the 248 nm photodissociation of this molecule [8].…”

IR diode laser spectroscopy was used to detect the products of HCNO (fulminic acid) photolysis at 193 nm. Six product channels are energetically possible at this photolysis wavelength: O + HCN, H + NCO/CNO, CN + OH, CO + NH, NO + CH and HNCO. In some experiments, isotopically labeled 15 N 18 O, C 2 D 6 or C 6 H 12 reagents were included into the photolysis mixture in order to suppress and/or redirect possible secondary reactions. HCN, OC 18 O, 15 N 15 NO, CO, DCN and HNCO molecules were detected upon laser photolysis of HCNO/reagents/buffer gas mixtures. Analysis of the yields of product molecules leads to the following photolysis quantum yields: φ 1a (O+HCN) = 0.38 ± 0.04, φ 1b (H + (NCO)) = 0.07 ± 0.02, φ 1c (CN + OH) = 0.24 ± 0.03, φ 1d (CO + NH(a 1 ∆)) < 0.22 ± 0.1, φ 1e (HNCO) = 0.02 ± 0.01 and φ 1f (CH + NO) = 0.21 ± 0.1, respectively.
