Python-Based Transient Absorption Spectroscopy Data Analysis (PyTrA) download

PyTrA combines many of the common fitting techniques used in ultrafast transient absorption spectroscopy in an easy to use package.

Transient absorption spectroscopy is a pump probe technique that provides details of how excited molecules’ absorbance changes just after being excited. In the Photon Factory, a pump pulse 150 fs in duration can be tuned to different single wavelengths to excite the molecules into their excited state. Then a probe pulse that contains a full spectrum of colour is used to take a snapshot of the absorbance of the molecules at set time intervals after their excitation. The probe can then be delayed relative to the pump and the decay in the excited molecules can be observed.
