One sentence summary:
Hydrogen bond complex formation of 2-pyridone in dichloromethane solution is unraveled in a combined approach exploiting NMR, steady-state FT-IR (including 2D correlation spectroscopy), femtosecond IR pump-probe wavepacket spectroscopy, and quantum chemical calculations.

One sentence summary:
Ultrafast IR spectroscopy of the NH and PO stretching bands of adenine–thymine base pairs in DNA oligomers enable to separate and assign DNA and water vibrations, to determine their couplings, and to unravel microscopic processes governing the dynamics of hydration shells.
