Chemical kinetics on extrasolar planets. [PDF]

Philos Trans A Math Phys Eng Sci, 2014
Abstract Chemical kinetics plays an important role in controlling the atmospheric composition of all planetary atmospheres, including those of extrasolar planets. For the hottest exoplanets, the composition can closely follow thermochemical-equilibrium predictions, at least in the visible and infrared photosphere at dayside (eclipse ...

Simple rules for resolved level-crossing spectra in magnetic field effects on reaction yields [PDF]

Magnetic Resonance, 2021
In this work we derive conditions under which a level-crossing line in a magnetic field effect curve for a recombining radical pair will be equivalent to the electron spin resonance (ESR) spectrum and discuss three simple rules for qualitative prediction
