The observation of non-adiabatic alignment of gas-phase molecules via an adapted opto-galvanic technique. — Christian Matthaei1,2, •Matthew S.

We have developed a new method for observing the non-adiabatic alignment of gas-phase molecules via an adapted opto-galvanic technique, in which the critical components of the detector are an oscilloscope and a 9V battery. In this talk I will discuss how we were able to observe the rotational wavepacket revivals of N2 and O2 molecules in a near-atmospheric pressure air mixture, after excitation by an ultrafast laser pulse, with high precision using this technique.
