The Wright group uses many class 3 and 4 lasers. First years who join the lab should be trained in standard laser safety procedures by a senior student. This guide provides a helpful introduction and should be read over before commencing lab work.
Below are links to papers which serve as an introduction to some of the projects and ideas the Wright group actively considers.
- Two good introductions to multidimensional spectroscopy are Multiresonant Coherent Multidimensional Spectroscopy and Optical Multidimensional Coherent Spectroscopy.
- Multidimensional spectroscopy is oftentime considered to be experimentally done in the "time domain" or "frequency domain" oftentimes, we find ourselves working at the interface between these domains. A comprehensive theoretical/numerical study in this mixed domain is Frequency-domain coherent multidimensional spectroscopy when dephasing rivals pulsewidth: Disentangling material and instrument response.
- The Wright Group uses and develops many different spectroscopies. These include transient grating, TG, (see Femtosecond transient-grating techniques: Population and coherence dynamics involving ground and excited states for a nice primer); triple sum frequency, TSF, (see Resonance IR: A Coherent Multidimensional Analogue of Resonance Raman); and Doubly Vibrationally Enhanced, DOVE, (Doubly Vibrationally Enhanced Four Wave Mixing: The Optical Analog to 2D NMR).
- The spectroscopies we use are built on nonlinear mixing of optical fields. Some of these mixing processes are not phase-matchable; a nice primer on phase-mismatch effects is Group- and phase-velocity-mismatch fringes in triple sum-frequency spectroscopy.
- We also specialize in building spectroscopies which are exquisitely sensative to coherence transfer events c.f. Frequency- and Time-Resolved Coherence Transfer Spectroscopy
The Wright group works on projects which involve charge-transfer species and biologically relevant metal centers. Good places to start reading about those projects include:
- Photolytic properties of cobalamins: a theoretical perspective
- Spectroscopically validated density functional theory studies of the B12 cofactors and their interactions with enzyme active sites
- On the Theory of Oxidation‐Reduction Reactions Involving Electron Transfer. III. Applications to Data on the Rates of Organic Redox Reactions
- Organic Mixed Valence
- We also do ultrafast spectroscopy of semiconductors. Nice introductions to those methadologies include:
