Complex organic molecules in strongly UV-irradiated gas. [PDF]
Astron Astrophys, 2017 We investigate the presence of COMs in strongly UV-irradiated interstellar molecular gas. We have carried out a complete millimetre line survey using the IRAM30m telescope towards the edge of the Orion Bar photodissociation region (PDR), close to the H2 dissociation front, a position irradiated by a very intense far-UV (FUV) radiation field.

X-Ray Analysis of Griseofulvin and Other Complex Organic Molecules [PDF]
, 1964 This thesis is concerned with x-ray structure determinations of complex organic molecules. In each case the phase problem has been surmounted by application of the heavy-atom method.

UV and VUV Ionization of Organic Molecules, Clusters, and Complexes [PDF]
The Journal of Physical Chemistry A, 2009 The generation of organic particle beams is studied in combination with photoionization using uv radiation at 266 nm and vuv light at 157 nm. Single-photon ionization with pulsed vuv light turns out to be sensitive enough to detect various large neutral biomolecular complexes ranging from metal-amino acid complexes to nucleotide clusters and aggregates

Performance of the M062X density functional against the ISOL set of benchmark isomerization energies for large organic molecules [PDF]
, 2010 Gas phase standard state (298.15 K, 1 atm) isomerization energies were calculated using the M062X functional with the QZVP, 6-311++G(d,p), 6-311++G(2d,2p), and cc-pVTZ basis sets against the 24 reactions in the ISOL set of benchmark isomerization ...

Complex organic molecules in protoplanetary disks [PDF]
Astronomy & Astrophysics, 2014 (Abridged) Protoplanetary disks are vital objects in star and planet formation, possessing all the material which may form a planetary system orbiting the new star. We investigate the synthesis of complex organic molecules (COMs) in disks to constrain the achievable chemical complexity and predict species and transitions which may be observable with ...

Complex organic molecules in organic-poor massive young stellar objects [PDF]
, 2015 Context. Massive young stellar objects (MYSOs) with hot cores are classic sources of complex organic molecules. The origins of these molecules in such sources, as well as the small- and large-scale differentiation between nitrogen- and oxygen-bearing ...

Collisional excitation of complex organic molecules [PDF]
Proceedings of the International Astronomical Union, 2008 AbstractA major difficulty in modelling the infrared and (sub)millimeter spectra of gas-phase complex organic molecules is the lack of state-to-state collisional rate coefficients. Accurate quantum or classical scattering calculations for large polyatomic species are indeed computationally highly challenging, particularly when both rotation and low ...

THE ORIGIN OF COMPLEX ORGANIC MOLECULES IN PRESTELLAR CORES
The Astrophysical Journal, 2014 Complex organic molecules (COMs) have been detected in a variety of environments, including cold prestellar cores. Given the low temperature of these objects, these last detections challenge existing models. We report here new observations towards the prestellar core L1544.

Energy level alignment and site-selective adsorption of large organic molecules on noble metal surfaces [PDF]
, 2006 In recent two decades, there has been a large interest in organic molecules on metallic as well as insulating substrates. This interest is caused by the need to understand fundamental properties of large organic molecules on solid surfaces at the level
