Dinitrogen monoxide N2O

Dinitrogen monoxide N2O is also called nitrous oxide, and emitted from natural and anthropogenic sources from the ground. Since N2O does not dissipate in the troposphere, it reaches to the stratosphere and subjects photolysis to provide reactive oxides of nitrogen (odd nitrogen). For this reason, the photolysis of N2O in the stratosphere is very important. 

As shown in Fig. 4.29, absorption spectmm of N2O is a broad continuum with a peak at around 180 nm, decreases monotonically toward longer wavelengths and extends to near 240 nm (Johnston and Selwyn 1975). Table 4.22 cites the absorption cross sections of N2O in the 160-240 nm region as recommended by NASA/JPL Evaluation No. 17 (Sander et al. 2011). These values are based on the data by Hubrich and Stuhl (1980) (160, 165, 170 nm), and Selwyn et al. (1977) (173-240 nm). The absorption cross sections are temperamre dependent and decrease with the increase of temperature for which the formula for approximation is given by Selwyn et al. (1977) (Sander et al. 2011). 

The following photolytic process has been known to occur with a quantum yield of unity for 140-230 nm covering the stratospheric photolysis region. 

To summarize the knowledge into a best estimate , the global N2O emission is calculated to be 12 5 Tg N yr of which anthropogenic activities (including biomass burning) contribute 40 %.

Nitrous oxide (dinitrogen monoxide N2O) is a colorless, odorless gas at room temperature (Figure 13-3). It is sold in steel cylinders and must be delivered through calibrated flow meters provided on all anesthesia machines. Nitrous oxide is neither flammable nor explosive, but it does support combustion as actively as oxygen does when it is present in proper concentration with a flammable anesthetic or material. 

Start with a binary molecular compound. Note that a binary molecular compound is composed only of two nonmetal atoms—not metal atoms or ions. An example is dinitrogen monoxide (N2O), a gaseous anesthetic that is more commonly known as nitrous oxide or laughing gas. The naming of nitrous oxide is explained in the following rules.
