Investigations of C60 and C70 nanoparticle interactions with amide functionality were carried by Fourier Transform Infrared Spectroscopy. A number of systems were studied, but the focus of this poster is on the methods and results of the formamide studies. Spectra were collected for neat formamide, formamide in a toluene environment, formamide in a C60 toluene environment, and formamide in a C70 toluene environment. A FTS7000 DigiLab infrared spectrometer and a ZnSe circle cell were used for spectral data collection. Significant challenges were encountered because of solubility compatibilities of reagents and special ATR spectral collection issues, and they are addressed in the poster. Shifts of the carbonyl stretching frequency to higher wavenumbers were observed when formamide was treated with both the C60 and C70: neat formamide, ~1665 cm-1; formamide/toluene, ~1669 cm-1, formamide/toluene C60 and C70, ~1676 cm-1.   These shifts suggest a weak intermolecular interaction between the amide functionality in formamide and the C60 and C70 nanoparticles.
