μIR spectra and powder XRD analysis of decomposition of LHP. a Variable-temperature powder X-ray diffraction pattern of LHP heated from room temperature to 150 °C. b The 2000‒800 cm‒1 region in the IR spectrum before (blue line) and after heating to 115 °C for 1120 s (red line). c Optical image of the LHP crystal used to record the μIR spectrum (the red circle indicates the position of the incident IR beam). The scale bar corresponds to 50 μm. d Time-profile of the IR spectrum of LHP at 115 °C. e Isothermal kinetic traces at selected wavenumbers (highlighted in d) used in the kinetic analysis
