Krypton immobilization

The electron paramagnetic resonance (EPR) spectrum of triplet imidogen immobilized in a cryogenic matrix has not yet been observed. One negative attempt was reported in argon, krypton, and xenon matrices in 1967. It would seem to be worthwhile for a new attempt in a xenon matrix.
