Abstract
Deposits of trinitrotoluene (TNT) prepared with an aerosol jet are examined with surface reflection Fourier transform infrared spectroscopy, scanning electron microscopy, atomic force microscopy and near field optical microscopy. Significant structure is observed in the vibrational spectrum of TNT particles in the N-O stretching region around 1530Â cmâ1 and in the spectroscopic finger print determined from transmission near field scanning optical microscopy (NSOM) measurements between 395 and 405Â nm as well as in the absorption spectra of bulk quantities of TNT. About 7Â fg of TNT are detected in the transmission NSOM measurements.
