Interactions between Nitric oxide (NO) and DDPA Langmuir-Blodgett (LB) film
are investigated with second harmonic generation(SHG) and atomic force mic
roscopy (AFM). It has been found that the adsorption of NO molecules on DDP
A LB film only changes the value of the second-order susceptibility of the
DDPA molecule on film but not its orientation.
