Looking at the explicit model calculations for THP, the transitions to the T2, T3, and T4 states exhibit practically equivalent intersystem crossing rates. In the case of resveratrone, the S1 → T2 transition has the most significant contribution to the ISC rate. In most cases, the calculated ISC rates in CPCM only and explicit solvent were equivalent. However, significant variations are observed in the ISC rate for the S1 → T1 employing these two solvation models. Such a strong dependence of ISC rates on explicit vs. implicit solvation has been previously reported in Ref. . As mentioned, the explicit solvation results should be considered the most accurate.
