β-Chain Hydrogen-Bonding in 4-Hydroxycoumarins
TL;DR: In the solid state, some 3-substituted 4-hydroxycoumarins β-ketoester enols form infinite translational hydrogen-bonded β-chains with varying degrees of alignment between adjacent delocalized systems as mentioned in this paper.

Quantum chemical study of tautomeric equilibriums, intramolecular hydrogen bonds, and π-electron delocalization in the first singlet and triplet excited states of 2-selenoformyl-3-thioxo-propionaldehyde
TL;DR: In this article , a detailed analysis of various tautomeric equilibriums, different types of hydrogen bonds, and π-electron delocalization was performed for 2-selenoformyl-3-thioxo-propionaldehyde (STP) in the first singlet and triplet excited states were investigated by CIS and TD-DFT methods.
