Phosphate arginine (PA) has been known as the medium carriers for bioenergy storage, while the similar structural substance L-arginine phosphate monohydrate (LAP) crystal is an excellent nonlinear optical crystal with a high laser-induced damage threshold. Energy storage in organism and laser-induced damage in crystals are both correlative to energy. Temperature dependence X-ray diffraction (XRD) and solid state NMR spectroscopy were performed to explore the impact of energy (heat and magnetic) fields on LAP crystal. XRD results reveal that LAP processes a reversible specific phase transition as the temperature changed. Saturation recovery experiments have shown that the crystal has a long proton spin-lattice relaxation time (1H T1) of 184 s with an amazing solid-state stability. The nuclear magnetic resonance (NMR) and fluorescence emission spectra of LAP solution compared with several amino salt solutions have also been investigated
