2016/12/13
Water conducts electricity, but the process by which this familiar fluid passes along positive charges has puzzled scientists for decades.But in a paper published in the Dec. 2 issue of the ...
Investigation Of The Orientation Dependence On Chiroptical Properties Of Single Molecules
chiral dipole emission fluorescence single molecule
2014/11/20
Optical activity is the defining property of chiral materials that is essential for characterization in biology, chemistry, and physics. While a substantial body of research has provided a strong theo...

Pure Rotational Molecular Spectra Asymmetric Molecules Chemical Physics
2012/4/24
In this paper we demonstrate how asymmetric molecular rotational spectra may be introduced to students both "pictorially" and with simple formulae. It is shown that the interpretation of such spectra ...
Making the best of mixed-field orientation of polar molecules: A recipe for achieving adiabatic dynamics in an electrostatic field combined with laser pulses
mixed-field orientation of polar molecules recipe adiabatic dynamics electrostatic field laser pulses Chemical Physics
