New research in Chemical Science shows that enhancement of intersystem crossing within DNA and RNA nucleobases is not significantly increased by substituting oxygen with sulfur, but rather through the carbonyl group with, as opposed to the heavier chalcogen!

Tautomer aspects in the excited-state dynamics in 2-thiocytosine: intersystem crossing in the absence of the thiocarbonyl group
Molecular tautomerism is ubiquitous in nature and plays a crucial role in regulating biological function. In nucleobases, for example, structural tautomerism not only influences base pairing and genetic coding in DNA but also modulates the molecular response to UV irradiation. The photostability of the nucle
