Sum-frequency generation (SFG) is a powerful vibrational spectroscopy that can selectively probe molecular structures at surfaces and interfaces, but its spatial resolution has been limited to the ...

Vibrational circular dichroism (VCD) has rapidly emerged as a critical chiroptical technique for elucidating the absolute configuration of chiral molecules. By measuring the differential absorption of ...
