Abstract
The circular dichroism spectra of (3R)-Methyl cyclohexanone and (3R)-Methyl cyclopentanone have been recorded in the range 2000-800 nm, covering the vibrational overtone for $\Delta$v=2, 3, 4. By comparing with the CD data for the same molecules at $\Delta$v=1 (1) and by considering the Birge-Sponer plots, a first assignement of the observed CD features will be proposed. Due comparison will be made with the CD data that had been previously collected for some cyclic monoterpenes in the near infrared range (2). In the latter case higher rotational strengths had been measured.
