Photon mol

These specific calculations yield the amount of 253.7 nm photons (mol photons) that are produced (under optimal conditions) during 1 h of irradiation with common industrial low-pressure or medium-pressure mercury lamps, respectively. Also, (Dp may be expressed in mol photons per second which is equivalent to the older unit einstein s-, or the number of photons per second emitted by the lamp can be calculated (Tab. 3-4). 

Photon exitance (Mp) The photon flow, (Dp, emitted by an element of the surface containing the source point under consideration divided by the area (S) of that element. (dconstant over the surface area considered). The SI unit is s mT. Alternatively, the term can be used with the amount of photons (mol or its equivalent einstein), the SI unit then being mol s uT. Also called specific photon emission. Formerly called photon emittance. 

Alternatively, the term can be used with the amount of photons (mol or its equivalent einstein), the SI unit then being mol m s . It reduces to photon irradiance for a parallel and normally incident beam not scattered or reflected by the target or its surroundings. 

We sometimes speak of a mole of photons, meaning 6.022 X 10-- packed of radiation of a given wavelength. The energy of a mole of photons with a wavelength of 5.00 ftra is then 6.022 X 10-- photons/mol photons X 3.98 X 10 -°J/photoa = 24.0 kj/mol photons. 

Figure 8.8 ECD and TPCD and OPA and TPA spectra for Si and S2 states of R3MCP computed with FCHTIVG and FCHTIAH models. All spectra are convoluted with aLorentzian broadening of 0.05 eV and obtained by averaging with Boltzmann weights the spectra of the individual conformers. Units are dm moP 1 photon mol for both TPCD and TPA.
