UVA-induced cyclobutane pyrimidine dimers in DNA: a direct photochemical mechanism? [PDF]
International audienceThe carcinogenic action of UVA radiation is commonly attributed to DNA oxidation mediated by endogenous photosensitisers. Yet, it was recently shown that cyclobutane pyrimidine dimers (CPD), well known for their involvement in UVB ...

Can acyclic conformational control be achieved via a sulfur-fluorine gauche effect? [PDF]
The gauche conformation of the 1,2-difluoroethane motif is known to involve stabilising hyperconjugative interactions between donor (bonding, σC-H) and acceptor (antibonding, σ*C-F) orbitals.
