The isothermal structural properties equation of state and vibrational dynamics of 2MNT were studied under high pressure using synchrotron XRD and optical Raman and IR microspectroscopy Analysis of the XRD patterns revealed no indication of a phase transition to near 15 GPa and the pressure volume isotherm remained smooth to 15 GPa Near 15 GPa significant sample damage was observed from the X ray beam which precluded the acquisition of patterns above this pressure XRD and Raman spectroscopic measurements showed the monoclinic ambient condition phase of 2MNT remains the dominant phase to near 20 GPa although a shift of the NO(2) IR active vibrational modes to lower frequencies suggested a subtle geometry modification not reflected in the XRD data
