Nuclear magnetic resonance impulse

Multidimensional nuclear magnetic resonance (NMR) techniques, since their inception in the 1970s, have turned into a powerful tool that provides structures and dynamics of very complex molecules, crystals, and proteins. By extending these ideas to the optical regime, it is possible to come up with novel classes of spectroscopies that can probe complex vibrational motions. Its realization, however, has to wait for the recent breakthrough in femtosecond laser techniques, which has provided necessary impulsive excitation to overcome tremendous line broad-...
