WebMolar circular dichroism [ edit] is the path length in centimeters (cm). is the molar circular dichroism. This intrinsic property is what is usually meant by the circular dichroism of the substance. Since is a function of wavelength, a molar circular dichroism value ( ) must specify the wavelength at which it is valid. WebN2 - In the present study, we have explored the mode of binding of an anti-leukemic drug, imatinib (IMT) mesylate with DNA and resulting conformational changes in DNA double helix. UV-Vis absorption, fluorescence and circular dichroism spectroscopic techniques were employed to study these interactions.
