Value, quick opening

P t) approaches an exponential in the limit v 00. The comparison with the experimental decay curves for two excitation energies is shown in Fig. 34 for several values oi u. It is evident that in both cases 1/ = 2 reproduces the experimental data well. Larger values of open channels suppress the smaller rates and therefore lead to curves, which fall off too quickly. However, u = 2 is significantly smaller than the predicted number of open adiabatic channels, which — for the PES of Ref. 271 — is about 8 for the average excess energy of 124 cm ... 

Health Elazards - Personal Protective Equipment Self-contained breathing apparatus protective clothing if exposed to liquid. Symptoms Following Etqjosure If concentration of gas in hi enough, may cause asphyxiation. No detectable systemic effects, even at 5 % concentration in air. Treatment for Exposure Remove victim to open air. If the is overcome by gas, qjply artificial resuscitation. Toxicity by Inhalation (Threshold Limit Value) Data not available Short-Term Inhalation Limits Data not available Toxicity by Ingestion Not pertinent Late Toxicity None Vapor (Gas) Irritant Characteristics Vapors are nonirritating to the eyes and throat. Liquid or Solid Irritant Characteristics No appreciable hazard. Practically harmless to the skin because it is very volatile and evaporates quickly. May cause some frostbite. Odor Threshold Data not available. 

Information about nonlinear absorptive properties of a sample can be derived simply by measuring the sample transmission as a function of the incident light intensity. We note that Eq. (5) can therefore be inverted to read T-1 = 1 + fi2LI a linear dependence of the inverse transmission on the incident intensity can be used to determine the j82 value. Because of the ease of determining the value of fi2 with open-aperture Z-scan, Z-scan is often the preferred method for quickly determining the nonlinear absorption coefficient. Point-by-point transmission measurements can be undertaken to verify the applicability of Eq. (5).
