Hammer, Nathan

Nathan Hammer, a chemistry professor at the University of Mississippi, uses vibrational Raman spectroscopy to help us understand the effects of intermolecular forces on molecular structure and behavior. The vibrational spectrum provides a valuable probe of the electron distribution in the molecules as well. In the spectra shown, for example, a vibrational transition in normal pyrimidine shifts from roughly 1570 cm (where it overlaps with another transition in the spectrum at left) to a clearly distinct peak at over 1580 cm (the spectrum at right) when a water molecule attaches to one of the nitrogen atoms. This upward shift occurs because some electron density transfers from a...
