Electron-enhanced vibrational spectroscopy: a theoretical approach.
Enhancement of the Raman scattering and IR absorption activities due to the electron-attachment was investigated for water systems by DFT calculations. DFT calculation of a 6-ring water cluster system that included the diffusive nature of electrons well reproduced the Raman enhancement effects and Raman shifts of the OH stretching modes observed in experiments. Based on the same model and calcu...
متن کاملSurface-Enhanced Impulsive Coherent Vibrational Spectroscopy
Surface-enhanced Raman spectroscopy (SERS) has attracted a lot of attention in molecular sensing because of the remarkable ability of plasmonic metal nanostructures to enhance the weak Raman scattering process. On the other hand, coherent vibrational spectroscopy triggered by impulsive excitation using ultrafast laser pulses provides complete information about the temporal evolution of molecula...
متن کاملVibrational ladder-climbing in surface-enhanced, ultrafast infrared spectroscopy.
In a recent work (J. Phys. Chem. C 2016, 120, 3350-3359), we have introduced the concept of surface-enhanced, two-dimensional attenuated total reflectance (2D ATR IR) spectroscopy with modest enhancement factors (<50) using small plasmonic noble metal nanoparticles at solid-liquid interfaces. Here, we show that employment of almost continuous noble metal layers results in significantly stronger...
متن کاملProbe enhanced, nano-Raman spectroscopy (PERS); A sensitive technique for vibrational surface spectroscopy
Vibrational spectroscopy, which is considered one of the most definitive means of obtaining chemical bonding information, often has a low measurement sensitivity preventing its application to the study of interfaces and monolayers. Surface plasmons induced on metal nano-particles by electromagnetic radiation (e.g. light) can be used to enhance the sensitivity and spatial resolution (below the o...
متن کاملVibrational Spectroscopy of C60
The fullerene era was started in 1985 with the discovery of the stable C60 cluster and its interpretation as a cage structure with the familiar shape of a soccer ball [1]. An explosive growth in fullerene research was triggered in 1990 by the development of a method to produce fullerenes in bulk quantities [2]. Subsequently, the structural, electronic, and vibrational properties of many fullere...
