    Abstract: Exposure of polycarbonate detectors to high γ- ray doses causes a great effect on their structural. Samples of Makrofol DE 1-1 nuclear track detectors (NTDs) were irradiated with gamma doses in the range of 1-100 kGy using 1.25 MeV 60Co source of dose rate 4 kGy/h. The optical characterization of these detectors have been studied through the measur... Show More

    Abstract: Three main tools are used to determine the structures of organic molecules. These tools are infrared (IR) spectroscopy, mass spectrometry (MS) and nuclear magnetic resonance (NMR) spectroscopy. Organic molecules absorb light (infrared, ultraviolet, etc.) at particular wavelengths based on different vibrational modes unique to the specific functiona... Show More
