Photoinduced absorption spectroscopy

SUMMARY

Photoinduced absorption spectroscopy involves a "pump" pulse of light followed by a "probe" pulse, allowing researchers to observe changes in electron structure over time. The discussion highlights the importance of understanding the term (delta)OD, which is plotted against time to analyze the dynamics of the sample. The need for precise referencing of academic papers is emphasized, specifically the requirement to include author, journal, volume, and page numbers for clarity and credibility in scientific communication.

PREREQUISITES
  • Understanding of photoinduced processes in spectroscopy
  • Familiarity with temporal resolution in femtosecond and picosecond measurements
  • Knowledge of optical absorption and its implications in material science
  • Ability to interpret scientific graphs and data representation
NEXT STEPS
  • Research the principles of femtosecond spectroscopy techniques
  • Learn about the significance of (delta)OD in spectroscopic analysis
  • Explore the methodologies for referencing academic papers correctly
  • Investigate the applications of photoinduced absorption spectroscopy in material characterization
USEFUL FOR

Researchers, physicists, and students in the fields of spectroscopy, material science, and photonics who seek to deepen their understanding of photoinduced absorption phenomena and their applications in scientific research.

I'm trying to comprehend a paper I'm supposed to summarize
this one:
---ok it won't let me post urls---- whatever

My question, is what is the deal with photoinduced absorption spectroscopy? I gathered that it involves a "pump" (burst of light) striking the sample and then a "probe" (another burst of light) striking the sample after the probe in the next few pico/fempto seconds. Watching what comes out tells you something about how the electron structure changes with time. But what is (delta)OD? There are graphs with time on the x-axis and this (delta)OD on the y. Can anyone explain what I'm looking at?
thanks
 
Physics news on Phys.org
what is the article reference (author/journal/volume/page)?

You should always post the exact reference to the paper, and I don't mean the url. If you don't know what that is, look at the references listed at the end of the paper you're reading and see how they are listed.
