Wasielewski Lab Facilities
Synthesis Labs
The Wasielewski Group is well-equipped to carry out synthetic chemistry procedures in 16 6-foot fume hoods with vacuum lines and a separate hood hosting an Expedite oligo nucleic acid synthesizer. Purified anhydrous solvents are easily accessible from the Glas-Contour column solvent purification system. Instrumentation rooms adjacent to the synthesis laboratories house benchtop equipment, such as a spin coater, analytical and preparative HPLC equipment (in both normal and reverse phase), a Shimadzu GC system, CH Instruments Model 660 and 750 single/dual channel electrochemical analysis systems. Air-sensitive chemistry can be carried out in two nitrogen glove boxes (MBraun); another nitrogen box is equipped with a vacuum thermal evaporator (Denton) for thin-film preparation.
Laser Labs
The Wasielewski group has a recently renovated state-of-the-art laser laboratory with 6 individual rooms with individual climate control. Each room is positively pressurized to reduce contamination and maintain tight control over temperature and relative humidity. Each room houses a laser system with dedicated experiments, including Femtosecond and Nanosecond Transient UV/VIS/NIR Absorption (fsTA/nsTA) Spectroscopy, Femtosecond and Nanosecond Transient mid-IR Absorption (fsIR) Spectroscopy, Two-Dimensional Electronic Spectroscopy (2DES), Femtosecond Stimulated Raman Spectroscopy (FSRS), and currently developing new setups for optically detected magnetic resonance (ODMR) and two-photon entangled spectroscopy. An example of one of our laser systems is shown in the tour below.
EPR Labs
Our lab features state-of-the-art EPR measurement capability at X-, Ka- and W-bands. We have three spectrometers capable of both steady state and time resolved EPR measurement. Some of our capabilities include: CW EPR and electron-nuclear double-resonance (ENDOR) spectroscopies; time-resolved CW EPR; pulsed EPR experiments such as electron-spin echo modulation (ESEEM), ENDOR; and multi-frequency experiments such as electron-electron double resonance (ELDOR) spectroscopy. For sample photo-excitation, the lab is equipped with two nanosecond Nd;YAG lasers whose output is each coupled to an optical parametric oscillaotor (OPO) to generate outputs at 355 nm and 416-650 nm.
