CD measurement of α-pinene gas in the vacuum UV region

The J-1500 CD spectrometer has recently been updated to provide better signal detection and resolution for a variety of sample choices. The enhanced optical system increases the light throughput and the new electronics include the latest in digital lock-in technology, which allows for a small signal in a very noisy environment to be detected. These features ensure that CD spectra can obtained by the J-1500 for strongly absorbing and high signal-to-noise (S/N) samples across the spectrum and into the vacuum-UV region.

The CD spectra measurement in the vacuum-UV region of (1R)-(+)-α-pinene gas and (1S)-(-)-α-pinene gas is reported in this application.
