The spectrum is obtained by subtracting the spectrum of the non-irradiated matrix from that of the irradiated matrix (1 h, 313 ± 10 nm). Positive bands: products, negative band: sulfine (2) S2
Figure S3. Photolysis of matrix isolated HOH CS complex in solid argon (11 K) with l = 254 nm. The spectrum is obtained by subtracting the spectrum before and after irradiation with λ = 254 nm (10 min). Positive bands: products, negative bands: HOH CS complex; lower part: computed IR spectrum of the complex (CCSD(T)/cc-pVTZ). S3
