Photodissociation of H₂⁺: variation with temperature

Rovibrationally resolved photodissociation of SH+

“…If the density of the environment is sufficiently high, then the populations of the v J levels may be assumed to be thermalized and it is appropriate to consider the so-called local thermodynamic equilibrium (LTE) cross section, [29], which depends only on the gas temperature T and the photon wavelength λ where k b is Boltzmann's constant, with the RV partition function given by 3.

STATE RESOLVED DATA FOR RADIATIVE ASSOCIATION OF H AND H + AND FOR PHOTODISSOCIATION OF ${\rm H}_2^+$

“…The cross section summed over all bound states (v, N) of H + 2 was given by Stancil et al (1993). The photodissociation cross sections for (2) were calculated by Oksyuk (1967), Dunn (1968a), Dunn (1968b), Argyros (1974), Stancil (1994), Lebedev & Presnyakov (2002), and Mihajlov et al (2007). Where individual data for select (v, N) levels and photon energies hν is given there is general agreement between their calculations.…”

“…Due to the J dependence of the Na; energy level, the internuclear distance R , for the dissociative transition is slightly shifted with J. Consequently the oscillations of the photodissociation cross section of a high vibrational level are also shifted on the photon energy scale when J increases. This effect has been theoretically studied in detail by Argyros (1974) in the case of H i ions. For instance at the wavelength 2220 A Argyros has found that the photodissociation cross section of the H i vibrational level U = 7 varies from its minimum to its maximum value when J increases from 0 to 8 (see figure 2 of Argyros 1974).…”
