Valence-Shell Electron-Pair Repulsion Theory (VSEPR)

If we let this system expand into three dimensions, however, we end up with a tetrahedral molecule in which the H-C-H bond angle is 109 o 28''. Repulsion between the five pairs of valence electrons on the phosphorus atom in PF 5 can be minimized by distributing these electrons toward the corners of a trigonal bipyramid .

What is Raman Spectroscopy? - HORIBA

Raman Spectroscopy is a non-destructive chemical analysis technique which provides detailed information about chemical structure, phase and polymorphy, crystallinity and molecular interactions. It is based upon the interaction of light with the chemical bonds
