The Petersen Group is focused on developing and utilizing novel nonlinear optical vibrational spectroscopies to directly probe ultrafast dynamics at surfaces and in the bulk.
Our research program is focused on developing and utilizing novel vibrational spectroscopies to directly probe ultrafast dynamics at surfaces and in the bulk. Time-resolved methods utilizing multiple laser pulses of femtosecond (10-15s or fs) duration facilitate studying molecular processes and chemical reactions on the natural time-scale of molecu...

An illustration of what chiral nonlinear spectroscopy reveals: that DNA is surrounded by a chiral water super-structure, forming a "spine of hydration." Water is the Earth’s most abundant natural resource, but it’s also something of a mystery due to its unique solvation characteristics – that is, how things ...
