Bond and mode selectivity in the reaction of atomic chlorine with vibrationally excited CH2D2.

The Journal of chemical physics

Bechtel HA, Kim ZH, Camden JP, Zare RN.
PMID: 15267915
J Chem Phys. 2004 Jan 08;120(2):791-9. doi: 10.1063/1.1630961.

The title reaction is investigated by co-expanding a mixture of Cl2 and CH2D2 into a vacuum chamber and initiating the reaction by photolyzing Cl2 with linearly polarized 355 nm light. Excitation of the first C-H overtone of CH2D2 leads...

Improved spatial resolution for reflection mode infrared microscopy.

The Review of scientific instruments

Bechtel HA, Martin MC, May TE, Lerch P.
PMID: 20059180
Rev Sci Instrum. 2009 Dec;80(12):126106. doi: 10.1063/1.3270260.

Standard commercial infrared microscopes operating in reflection mode use a mirror to direct the reflected light from the sample to the detector. This mirror blocks about half of the incident light, however, and thus degrades the spatial resolution by...

Ultrafast dynamics of vibrational symmetry breaking in a charge-ordered nickelate.

Science advances

Coslovich G, Kemper AF, Behl S, Huber B, Bechtel HA, Sasagawa T, Martin MC, Lanzara A, Kaindl RA.
PMID: 29202025
Sci Adv. 2017 Nov 24;3(11):e1600735. doi: 10.1126/sciadv.1600735. eCollection 2017 Nov.

The ability to probe symmetry-breaking transitions on their natural time scales is one of the key challenges in nonequilibrium physics. Stripe ordering represents an intriguing type of broken symmetry, where complex interactions result in atomic-scale lines of charge and...

Much of the electronic transport, photophysical, or biological functions of molecular materials emerge from intermolecular interactions and associated nanoscale structure and morphology. However, competing phases, defects, and disorder give rise to confinement and many-body localization of the associated wavefunction,...
