General description

3-Methylcyclopentanone is a monocyclic ketone and its optical rotatory dispersion has been studied under isolated and solvated conditions to explore the role of ring size/morphology. The vibrationally resolved electronic circular dichroism (ECD) spectra of (R)-(+)-3-methylcyclopentanone in gas phase was evaluated by density functional theory.

The optical rotatory dispersion of two monocyclic ketones, (R)-3-methylcyclopentanone [R-3MCP] and (R)-3-methylcyclohexanone [R-3MCH], has been investigated under isolated and solvated conditions to explore the role of ring size/morphology and to elucidate the impact of environmental perturbations. Vapor-phase measurements of specific
