Question
The following abstract is for the laser-induced fluorescence experiment in pyrene. Critique it as if you were peer reviewing it for publication in J. Phys. Chem. Give both general criticism pertaining to content and style as well as specific criticism regarding technical issues. To make it a bit easier, I propose that you do this in bullet form – in other words, just list comments (both positive and negative, please) without worrying about writing full sentences and organizing them into a formal review. It would be valuable, however, if you prioritize your comments (most important ones first).
"We report time-resolved fluorescence studies of pyrene. A pulsed nitrogen laser is used to excite the samples. The laser operates using an electrical discharge that excites nitrogen vapor to create a population inversion. Amplification of spontaneous emission leads to 3 mJ pulses of 200 ps duration at 337 nm. Fluorescence from pyrene is observed and time-resolved using a PMT with a 50 ohm termination. The emission is spectrally resolved with a monochromator having 0.5 mm slit width. We find that the light emission can be decomposed into a single molecule and an excimer component. The former has blue emission and 75.45 +/- 2 ns decay time while the latter has green emission and substantially longer lifetime. The literature value of the single molecule lifetime component has been reported to be 60 +/- 10 ns, in reasonable agreement with our measurement."
Explanation / Answer
1) Well written, no grammatical error.
2) Description of setup and its working principle has been discussed.
3)The lifetime of excimer component has not been provided.
4)Accuracy is more in the case of reported result.
