General description
The rotational spectrum of 2-butynoic acid was measured by pulsed supersonic-jet Fourier transform microwave spectroscopy.
Application
2-Butynoic acid was employed as synthon in a variety of reactions, including cycloacylation of phenols to flavones and chromones, and cyclization to γ-butyrolactones. It was also used in synthesis of Z-trisubstituted olefins via γ-alkylation.

The application of FTIR spectroscopy to concentrated solutions of tetrolic acid shows, for the first time, a direct relationship between molecular self association in solution and H-bonded motifs in the subsequently crystallised solid phases.

Adhesive bonding of resins to dentin surfaces requires the removal of the layer of debris caused by the cutting. Certain isotonic acidic solutions can do this rapidly. Five solutions were evaluated using cell cultures and pulp studies in monkeys. At

The solution behavior of a model compound, tetrolic acid (TTA), is studied via molecular dynamics simulations in four organic solvents. The results suggest that strong interactions between TTA and solvent molecules (ethanol or dioxane) prevent the formation of carboxylic acid
