In the present study, seven novel explosive mols. (nitroimidazoles) have been investigated for laser induced breakdown (LIB) spectral signatures of mol. and at. species in air and argon atmospheres utilizing both femtosecond (fs) and nanosecond (ns) laser pulse excitation. The mol. emissions were observed to be stronger in the fs spectra whereas at. emissions were prominent in the ns spectra recorded in both air and argon atmospheres. The C2 Swan band was strongest in an argon atm. while the CN violet band was strongest in ambient environment. The LIB spectra were analyzed for understanding (a) the influence of mol. structure i.e. type of bonds (C-C, C=C, C-N and C=N) on at. (C, H, N and O) and mol. (CN, C2 and NH) emissions, (b) effect of surrounding atm. on the fs and ns LIB spectra, (c) correlation between stoichiometric and intensity ratios of mol. as well as at. species, (d) effect of the number of substituents and their position in the ring on the fragmentation pathways and (e) correlation between oxygen balance and LIB spectra. Furthermore, time resolved spectroscopic studies of the plasma induced by fs and ns laser pulses have been carried out to understand the temporal evolution and possible reaction mechanisms of various mol. species. An attempt has been made to correlate the spectral emission with the chem. structure for this series of energetic materials. Our detailed studies and analyses clearly suggest that the atomization/fragmentation ratio could serve as a performance metric for high energy materials. In the experiment, the researchers used many compounds, for example, 1-Methyl-4-nitroimidazole (cas: 3034-41-1Recommanded Product: 3034-41-1).
1-Methyl-4-nitroimidazole (cas: 3034-41-1) belongs to imidazole derivatives. Many natural products, especially alkaloids, contain the imidazole ring. These imidazoles share the 1,3-C3N2 ring but feature varied substituents. Imidazole also acts as a microtubule destabilizing agents and inhibits topoisomerase and Cytochrome P450 Family 26 Subfamily A Member 1 (CYP26A1) enzymes.Recommanded Product: 3034-41-1
