Photodissociation of o-bromotoluene at 266 nm [PDF]

, 1999
The photodissociation of o-bromotoluene at 266 nm has been investigated using the universal crossed laser-molecular beam technique. The angle-resolved time-of-flight (TOF) spectra corresponding to Br photofragment are measured at different lab angles ...

Theoretical Investigation of Transient Species following Photodissociation of Ironpentacarbonyl in Ethanol Solution [PDF]

Photodissociation of ironpentacarbonyl in solution generates transient species in different electronic states, which we have studied theoretically. From ab initio molecular dynamics simulations in ethanol solution, the closed-shell parent compound Fe(CO ...

The Molecular Cloud Life Cycle. I. Constraining H2 Formation and Dissociation Rates with Observations

The Astrophysical Journal
Molecular clouds (MCs) are the birthplaces of new stars in galaxies. A key component of MCs are photodissociation regions (PDRs), where far-ultraviolet radiation plays a crucial role in determining the gas’s physical and chemical state.

Absorption spectroscopy of AlO including photodissociation [PDF]

Photodissociation of AlO may be important for the aluminium chemistry in various astrophysical regions. The photodissociation cross sections and rates of AlO were investigated over the temperature range from 0 to 15000 K in this work.
