Spectroscopy Spotlight
Resonant surface-enhanced infrared spectroscopy (resonant SEIRA) overcomes the limitation of traditional Fourier transform IR (FT-IR) spectroscopy for minute sample sizes of low infrared absorption cross-sections (relatively low absorptivity). This technique provides orders of magnitude enhancement in the detection of infrared vibrations of molecules located in the proximity of resonantly excited (plasmon related) electromagnetic fields. We recently interviewed Frank Neubrech, PhD, postdoctoral research associate at Heidelberg University working with Professor Harald Giessen at the 4th Physics Institute at Stuttgart University, in Germany, regarding this research. read more
