Irradiation Investigation: Exploring the Molecular Gas in NGC 7293

Galaxies, 2020
Background: Many planetary nebulae retain significant quantities of molecular gas and dust despite their signature hostile radiation environments and energetic shocks.

Sigma*-mediated electronic relaxation in 200nm photoexcited ammonia and heteroaromatics

EPJ Web of Conferences, 2013
Time–resolved photoelectron spectra of ammonia display combination bands of the umbrella and stretching modes associated with the N–H coordinate of σ* relaxation. Time–resolved photodissociation studies determine timescales

Photodissociation dynamics of HCOOH(Ã)

Chemical Physics Letters, 1988
The technique of Doppler-resolved, polarised LIF spectroscopy has been employed in a study of the energy and momenta disposal in the OH fragments generated via photodissociation of HCOOH (A 1A″) at 225 nm. The majority of the excess energy resides in fragment translation (≈ 78%) and internal excitation of the HCO fragment (≈ 12%).

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.

Hydroxyl super rotors from vacuum ultraviolet photodissociation of water

Nature Communications, 2019
Free electron lasers provide a state-of-the-art tool to investigate the photochemistry of water. Here, the authors show that highly rotationally excited hydroxyl radicals, so-called “super rotors” existing above the bond dissociation energy, are observed

Simulation of carboxymyoglobin photodissociation.

Journal of Biological Chemistry, 1986
Computer-generated models of the structures of deoxymyoglobin and CO-bound myoglobin show that the CO molecule is not packed so tightly by the amino acid residues of the distal pocket to prevent its motion away from the iron atom upon photodissociation.
