Molecular ion trap-depletion spectroscopy of BaCl$^+$

, 2011
We demonstrate a simple technique for molecular ion spectroscopy. BaCl$^+$ molecular ions are trapped in a linear Paul trap in the presence of a room-temperature He buffer gas and photodissociated by driving an electronic transition from the ground X$^1 ...

The Photodissociation and Ionization Fronts in M17-SW Localized with FIFI-LS on Board SOFIA

The Astrophysical Journal, 2023
To understand star formation rates, studying feedback mechanisms that regulate star formation is necessary. The radiation emitted by nascent massive stars play a significant role in feedback by photodissociating and ionizing their parental molecular ...

The photodissociation of CO in circumstellar envelopes

, 2017
Carbon monoxide is the most abundant molecule after H$_2$ and is important for chemistry in circumstellar envelopes around late-type stars. The size of the envelope is important when modelling low-J transition lines and deriving mass-loss rates from such

Pulsed Laser Synthesis of Carbon Nanostructures from Organic Molecular Liquids: Structure, Kinetics and Photophysical Properties

Advanced Science, EarlyView.
The non‐focused nanosecond pulsed laser irradiation of aromatic liquids produces amorphous carbon nanodots (CNDs) or curved‐graphene quantum dots (c‐GQDs) by surface‐catalyzed 0‐order reactions under kinetic control. C hybridization partially changes from sp2 to sp3. O‐based groups passivate the surface.

Destruction of Refractory Carbon in Protoplanetary Disks [PDF]

, 2017
The Earth and other rocky bodies in the inner solar system contain significantly less carbon than the primordial materials that seeded their formation. These carbon-poor objects include the parent bodies of primitive meteorites, suggesting that at least ...

Photoallylation Mechanism of Dicyanobenzenes with Allyltrimethylsilane in Solution Investigated by Cold UV and IR Spectroscopy in the Gas Phase

Chemistry – An Asian Journal, EarlyView.
The structure of the chemical intermediate in photoallylation of dicyanobenzenes (DCBs) with allyltrimethylsilane (ATMS) in acetonitrile was determined by cold UV and IR spectroscopy in the gas phase. The reaction mechanism was discussed on the basis of the intermediate structure. It was found that the elimination of a CN group from the intermediate is

Ultrafast F2− photodissociation by intense laser pulses: a time-resolved fragment imaging study [PDF]

EPJ Web of Conferences, 2019
We present time-resolved coincidence imaging of F2− photodissociation by 400nm and intense 800nm ultrafast pulses. Coincidence fragment imaging reveals parallel and perpendicular single photon dissociation on 2Σg+ and 2πg states, and additional intense ...
