Optical Chirality Measurement of the Interface

Optical chirality of molecules is a characteristic measure of stereo-chemical property of biological, pharmaceutical, and metal coordination compounds. Choral structures of amino acids, proteins, DNAs, and various drugs in solutions have been determined from the measurement of circular dichroism (CD). However, small amount of molecules at the liquid-liquid interfaces has never been measured before CLM/CD method [19] and SHG/CD method have been reported [20], 

Most selective technique to measure the optical chirality at the interface will be the SHG/CD spectroscopy, as demonstrated by a pioneering work of Hicks and
