Term symbols for molecules Syntax: 2S+1|ML| ML = ml , S = s ml = 0 ( from s or pz orbitals), ml = ±1 ( from px, py-orbitals) • Simplified by the selection rules – no electron with same quantum number set!! Spectroscopy • Absorption/Emission of energy in the form of a wave-particle duality – happens at UV-vis and IR-wavelengths – most often involves the ground state Ø Boltzman distribution • Drives Chemistry in the Atmosphere! – solar input is converted to • higher chemical potential (entropy radicals) • higher kinetic energy S o lar S p ectru m from Boeker and van Grondelle: Environmental Physics O xygen electronic states from Finlayson-Pitts and Pitts: Chemistry of the upper and lower Atmosphere O xygen electronic states from Finlayson-Pitts and Pitts: Chemistry of the upper and lower Atmosphere
