HCN is a key ingredient for synthesizing biomolecules such as nucleobases and amino acids. We calculate 42 reaction rate coefficients directly involved with or in competition with the production of HCN in the early Earth or Titan atmospheres. These reactions are driven by methane and nitrogen radicals produced via UV photodissociation or lightning. For every reaction in this network, we calculate rate coefficients at 298 K using canonical variational transition state theory (CVT) paired with… Expand

CRAHCN-O: A consistent reduced atmospheric hybrid chemical network oxygen extension for hydrogen cyanide and formaldehyde chemistry in CO2-, N2-, H2O-, CH4-, and H2-dominated atmospheres.
An oxygen extension to the consistent reduced atmospheric hybrid chemical network is developed, building off the previously developed network for HCN production in N2-, CH4- and H2-dominated atmospheres (CRAHCN), which can be used to simulate both HCN and H 2CO production in atmospheres dominated by any of CO2, N2, H2O, CH4, and H1.

Hydrogen cyanide in nitrogen-rich atmospheres of rocky exoplanets
Abstract Hydrogen cyanide (HCN) is a key feedstock molecule for the production of life's building blocks. The formation of HCN in an N2-rich atmospheres requires first that the triple bond betweenExpand

The reaction of nitrogen atoms with methyl radicals: Are spin-forbidden channels important?
According to the calculations, spin-forbidden processes are highly unlikely for the N(4S) + CH3 reaction, however, further evolution of the preferred products, H2CN+H, might explain the experimental observation of hydrogen cyanide as a minor product in this reaction. Expand
