Abstract
The invention relates to novel radical lithium phthalocyanine crystals, their preparation process and their use for in vivo determination of molecular oxygen. These radical lithium phthalocyanine crystals comply with the formula: ##STR1## in which R.sup.1 and R.sup.2, which can be the same or different, represent a deuterium or hydrogen atom having a tetragonal crystalline structure belonging to the space group P4/mcc. They are usable for in vivo oxygen determination by EPR spectrometry.
