IsoPlane Spectrograph Used in Raman Research
News Nov 05, 2013
Princeton Instruments has announced that the award-winning IsoPlane spectrograph has been used in recent, research in single-molecule tip-enhanced Raman spectroscopy by the Van Duyne group at Northwestern University.
Sonntag et al., “The Origin of Relative Intensity Fluctuations in Single-Molecule Tip-Enhanced Raman Spectroscopy,” has recently been accepted for publication by The Journal of the American Chemical Society (DOI: 10.1021/ja408758j).
The researchers combined the techniques of single molecule tip-enhanced Raman spectroscopy (SMTERS) and scanning tunneling microscopy (STM) to obtain unprecedented sensitivity and spatial resolution in Raman spectra of single rhodamine 6G molecules.
The results constitute a significant advance in the understanding of excited-state dynamics in adsorbate-substrate interactions.
The experimental setup included the PIXIS 400B CCD camera and IsoPlane SCT-320 spectrograph from Princeton Instruments.
