In an article, published in an article, once mentioned the application of 19752-84-2, Name is Tetrahydro-2H-pyran-3-ol,molecular formula is C5H10O2, is a conventional compound. this article was the specific content is as follows.Computed Properties of C5H10O2
The far-infrared spectra in the region of 50-450 cm-1 are reported for the vapours of cyclohexanone and the structurally related compounds tetrahydro-4H-pyran-4-one, tetrahydro-4H-thiopyran-4-one, tetrahydro-4H-pyran-3-one, 1,3-dioxan-5-one, and 4H-pyran-4-one.Except for the last mentioned, the spectra are characterized by two or in some cases three sequences of Q branches which are assigned to the out-of-plane deformations of the cyclohexanone ring.The lowest wavenumber sequence in each compound is believed to arise from a vibration which, if completely executed, would take the chair conformation to its equivalent via an inversion through the planar form.Each sequence is amenable to solution by a one-dimensional Hamiltonian incorporating a quadratic-quartic potential function, providing estimates for the magnitudes of the barriers to planarity.
