γ‐Irradiation of tris (methylidene)‐cyclopropane (‘[3]radialene’) 1 in a rigid electron scavenging matrix (butylchoride/i‐pentane, 1:1) at 77 K leads to formation of its molecular cation 1 + . Slight softening of the matrix by a temperature increase of 3–5 K results in formation of a newly absorbing species, tentatively assigned arising from structrral relaxation of 1 + by π‐bond rotation:
