# PHOTOLYSIS REACTIONS - MASTER RATEFILE - Paul Brown, Oliver Wild & David Rowley # Centre for Atmospheric Science, Cambridge, U.K. Release date: 22 November 1993 # SCCS version information: @(#)photol.d 1.2 5/11/94 # # REVISION HISTORY: # ----------------- # (1) Modified for Harvard chemistry: several reactions added, re-ordered per chem.dat # Also putting in the Harvard names in col 1, the UCI x-sec names in last col !!! # -Prashant Murti [4/13/98] # # (2) The new peroxide recycling now activates the following photolysis species: # GP,IAP,INPN,ISN1,ISNP,MAOP,MRP,PP,PRPN,RIP,VRP. # Also be sure to set parameter JPMAX = 55 in "cmn_fj.h". # - Randall Martin & Bob Yantosca [12/20/00] # # (3) New updates from FASTJX. (jmao,ccarouge, 04/20/09) # # (4) Updated the branching ratio of HNO4. Changed the lines: # Line 13 HNO4 from 33.3 to 5.0 # Line 14 HNO4 from 66.7 to 95.0 # This is based on Jimenez et al, "Quantum yields of OH, HO2 and NO3 # in the UV photolysis of HO2NO2" (jmao, bmy, 10/27/09) # # # Harvard species Products - UCI notation UCI xsec # =============== =============================== ======== 1 H2O PHOTON OH HO2 0.00E+00 0.00 0.0 2 HO2 PHOTON OH O(3P) 0.00E+00 0.00 0.0 3 O2 PHOTON O(3P) O(3P) 0.00E+00 0.00 100.0 O2 4 O3_P PHOTON O2 O(3P) 0.00E+00 0.00 100.0 O3 5 O3 PHOTON O2 O(1D) 0.00E+00 0.00 100.0 O3_1d 6 NO2 PHOTON NO O(3P) 0.00E+00 0.00 100.0 NO2 7 H2O2 PHOTON OH OH 0.00E+00 0.00 100.0 H2O2 8 MP PHOTON HCHO OH HO2 0.00E+00 0.00 100.0 ROOH 9 CH2O PHOTON CO HO2 HO2 0.00E+00 0.00 100.0 HCHO=H+ 10 CH2O PHOTON CO H2 0.00E+00 0.00 100.0 HCHO=H2 11 HNO3 PHOTON OH NO2 0.00E+00 0.00 100.0 HONO2 12 HNO2 PHOTON OH NO 0.00E+00 0.00 100.0 HONO 13 HNO4 PHOTON OH NO3 0.00E+00 0.00 5.0 HO2NO2 14 HNO4 PHOTON HO2 NO2 0.00E+00 0.00 95.0 HO2NO2 15 NO3 PHOTON NO O2 0.00E+00 0.00 100.0 NO3=O2+ 16 NO3 PHOTON NO2 O(3P) 0.00E+00 0.00 100.0 NO3=O+ 17 N2O5 PHOTON NO3 NO O(3P) 0.00E+00 0.00 0.0 N2O5 18 N2O5 PHOTON NO3 NO2 0.00E+00 0.00 100.0 N2O5 19 ALD2 PHOTON CH4 CO 0.00E+00 0.00 100.0 Acet=R+ 20 ALD2 PHOTON MeOO HO2 CO 0.00E+00 0.00 100.0 Acet=RO 21 PAN PHOTON MeCO3 NO2 0.00E+00 0.00 100.0 PAN 22 RCHO PHOTON EtO2 HO2 CO 0.00E+00 0.00 100.0 RCHO 23 ACET PHOTON MeCO3 MeOO 0.00E+00 0.00 100.0 AcetA 24 ACET PHOTON MeOO MeOO CO 0.00E+00 0.00 100.0 AcetB 25 MEK PHOTON MeCO3 EtOO 0.00E+00 0.00 100.0 EtCOMe 26 MNO3 PHOTON HCHO H2O NO2 0.00E+00 0.00 100.0 MeNO3 27 GLYC PHOTON HCHO HO2 CO 0.00E+00 0.00 100.0 HOMeCHO 28 GLYX PHOTON H2 CO HCHO 0.00E+00 0.00 100.0 Glyxla 29 GLYX PHOTON CO HO2 0.00E+00 0.00 100.0 Glyxlb 30 MGLY PHOTON MeCO3 CO HO2 0.00E+00 0.00 100.0 MeCOCHO 31 MGLY PHOTON Acet CO 0.00E+00 0.00 0.0 MeCOCHO 32 MVK PHOTON PRPE CO 0.00E+00 0.00 60.0 MeCOVi 33 MVK PHOTON MeCO3 HCHO CO HO2 0.00E+00 0.00 20.0 MeCOVi 34 MVK PHOTON MeOO MAO3 0.00E+00 0.00 20.0 MeCOVi 35 MACR PHOTON MAO3 HO2 0.00E+00 0.00 50.0 MACR 36 MACR PHOTON CO HO2 MGLY HO2 MeCO3 HCHO 0.00E+00 0.00 50.0 MACR 37 HAC PHOTON MeCO3 HCHO HO2 0.00E+00 0.00 100.0 AcetA 38 ETP PHOTON OH HO2 Acet 0.00E+00 0.00 100.0 ROOH 39 RA3P PHOTON OH HO2 RCHO 0.00E+00 0.00 100.0 ROOH 40 RB3P PHOTON OH HO2 RCHO 0.00E+00 0.00 100.0 ROOH 41 R4P PHOTON OH HO2 RCHO 0.00E+00 0.00 100.0 ROOH 42 RP PHOTON OH HO2 Acet 0.00E+00 0.00 100.0 ROOH 43 R4N2 PHOTON NO2 MeCOMe MEK MO2 HO2 ALD2 ... 0.00E+00 0.00 100.0 MeNO3 44 MAP PHOTON OH MO2 0.00E+00 0.00 100.0 ROOH 45 INPN PHOTON OH HO2 RCHO NO2 0.00E+00 0.00 100.0 ROOH 46 PRPN PHOTON OH HO2 RCHO NO2 0.00E+00 0.00 100.0 ROOH 47 PP PHOTON OH HO2 RCHO 0.00E+00 0.00 100.0 ROOH 48 GP PHOTON OH HO2 RCHO 0.00E+00 0.00 100.0 ROOH 49 GLP PHOTON OH HO2 RCHO 0.00E+00 0.00 100.0 ROOH 50 RIP PHOTON OH HO2 CH2O MVK MACR RIO1 IALD 0.00E+00 0.00 100.0 ROOH 51 IAP PHOTON OH HO2 CO H2 HAC GLYC MGLY 0.00E+00 0.00 100.0 ROOH 52 ISNP PHOTON OH HO2 RCHO NO2 0.00E+00 0.00 100.0 ROOH 53 VRP PHOTON OH HO2 CH2O MCO3 GLYC MGLY 0.00E+00 0.00 100.0 ROOH 54 MRP PHOTON OH HO2 MGLY HAC CO CH2O 0.00E+00 0.00 100.0 ROOH 55 MAOP PHOTON OH HO2 RCHO 0.00E+00 0.00 100.0 ROOH 9999 0.00E-00 0.00 0.0 NOTES: ----- [4/15/98] Oliver Wild: All reaction data from JPL '97, IUPAC IV. IUPAC V is soon expected. - ppm All reaction data taken from IUPAC supplement IV unless otherwise indicated. JPL - data from JPL (latest assessment as far as possible) ? - reaction products unknown * - user strongly advised to consult source material B - branching ratio assumed equal for all channels in the absence of more information U - upper limit for rate coefficient Changes since 08/3/93 release: O now written as O(3P) (Note that the second of the acetaldehyde channels above occurs at wavelengths less than 289 nm, and therefore doesn't appear in the Fast-J region at all - I've simply included it here for completeness) - [from Oliver, 3/7/98]
