Guaiazulene was irradiated with γ-rays at a constant dose rate and its absorption spectrum was compared with those of the compounds irradiated at different dose rates. There was almost no changes according to difference in dose rates, and absorption intensity tended to decrease with increasing irradiation dose. Irradiation of a solution of different concentrations of 10^<-1>, 10^<-2>, and 10^<-3> M at the same dose level indicated that a dilute solution is more liable to be affected. A 10^<-2> M solution was irradiated with 10^7 and 10^8 r, the solution was evaporated, and the sample was submitted to elemental analysis. Analytical values suggested that guaiazulene has been reduced and the product did not form a crystalline addition compound with picric acid or 1,3,5-trinitrobenzene. In the infrared spectra, the peaks at 1562 and 1532 cm^<-1>, which are considered to indicate the azulene skeleton, were absent in the spectrum of the irradiated sample, in which a new peak appeared at 1698 cm^<-1>.
