ASSIGNED ! DO NOT OVER-WRITE. CONTAINS PRIMARY ASSIGNMENTS AND DOCUMENTATION ! Assigned mechanisms for species that react only with OH and are ! are appropriately lumped with aromatics in condensed mechanisms. ! ! Inclucludes following assigned mechanisms: ! TDI, P-TI, MDI ! PARMS 10 OHRR OHNR OHA1 OHBL OHXC OHXN OHHO OHCR OHMG OHA3 ! ! Reactions of TDI, P-TI and MDI based on parameterized mechanisms in ! TDI and MDI reports, with some parameters modified based on fits to ! chamber data with SAPRC-99 mechanism. ! TDI K(OH) 7.4E-12 OHHO 0.5 OHCR 1.0 ! Based on mechanism used in TDI report except that the OH yield was ! increased based on simulations of the chamber data. P-TI K(OH) 5.9E-12 OHHO 0.2 OHRH 0.7 OHMG 0.15 OHCR 1.0 ! "Best estimate" mechanism from MDI report. MDI K(OH) 1.18E-11 OHHO 0.2 OHRH 0.7 OHMG 0.15 OHCR 1.0 ! Based on PTI mechanism with kOH doubled
