Abstract:
Here, we demonstrated photoinduced NO generation from a 2,6-dimethylnitrobenzene-based compound (Flu-DNB) via a two-photon excitation (TPE) process. After pulse laser irradiation to a solution of Flu-DNB, oxidation products of NO were observed. This is the first account of a non-nitrosyl-chelated metal ion containing NO donor which can be controlled by the TPE technique.

Rate-Determining Steps
In a multistep reaction mechanism, one of the elementary steps progresses significantly slower than the others. This slowest step is called the rate-limiting step (or rate-determining step). A reaction cannot proceed faster than its slowest step, and hence, the rate-determining step limits the overall reaction rate.
The concept of rate-determining step can be understood from the analogy of a 4-lane freeway with a short-stretch of traffic-bottleneck caused due to...
