Molecular force measurement in liquids and solids using vibrational spectroscopy
Article Abstract:
Intermolecular forces in liquids and solids as a function of external pressure are measured via shifts in molecular vibrational frequencies. The method relies on a predicted proportionality of the measured frequency shift and the mean force along the vibrating bond, with a coefficient depending only on properties of the isolated solute. Pronounced differences between the forces experienced by different types of bonds, with only a weak dependence on the location of the bond within the solute or the molecular structure of the surrounding solvent, were observed.

Revisiting Bohr's semiclassical quantum theory
Article Abstract:
Bohr's semiclassical quantum theory is revisited and the application of Bohr's original strategy to the three quintessential quantum systems, namely an electron in a box, an electron in a ring, and a dipolar harmonic oscillator, are demonstrated. The results raise provocative questions concerning the origin of quantum-chemical phenomenon, and also prove to be of pedagogical value in introducing students to quantum mechanics.
