Radial frequency photon energy

The function e(i ) itself is dimensionless. Frequency is in radians per second, but for compactness is often written in units of electron volts (the energy of a photon with that same radial frequency). If a quantity is tabulated in units of electron volts, it can be converted to radians per second by multiplying by 1.519 x 1015 (e.g., Level 1, the table on the frequency spectrum). This holds for the quantities coj and gj, which are given in electron volts. The numerator f is given in electron volts squared [to keep e(/ ) dimensionless] and can be converted to (radians/second)2 if one chooses to work in those units through multiplying by (1.519 x 1015)2. In the Debye form d -/( 1 + r ), the numerator dj is dimensionless and the inverse relaxation time 1 /r - is in electron volts. 

Problem Ll.l How important is temperature in determining which sampling frequencies act in the charge-fluctuation force For n = 1,10, and 100, compute imaginary radial frequencies i(T) at T = 0.1,1.0,10,100, and 1000 K with corresponding frequencies vt(T), photon energies (T), and wavelengths Xi. 

We report on the influence of a short-wave laser radiation on the properties of SWCNTs. This effect is confirmed by considerable increase of the intensities of 2vq and 2vd harmonics and of low-frequency radial mode Vr in their Raman spectra under increase of the energy of exciting photons. While the G-band intensity remains almost the same, the intensity of the 2vd band increases 1.7 times under excitation with 476.5 nm in comparison with 514.5 nm. Excitation with the 476.5 nm laser beam also leads to increase of the side bands in the fine structure of the Vd mode as well as Vd+Vg and Vg+Vrbm harmonics. We demonstrate that...
