Book Description
Use of LIF in two line thermometry TLT and of flash lamp absorption to examine high enthalpy flows is presented. The aim is to measure rotational and vibrational temperatures of nitric oxide NO in high temperature air in the Goettingen High Enthalpy Shock Tunnel HEG. Theory of NO (energy levels, spectroscopy, level populations), LIF and TLT are discussed. Results are given from a test cell to validate TLT with NO LIF as a quantitative technique. HEG results for rotational and vibrational temperatures in the free stream and around models are presented. Finally, flash lamp absorption results yielding these temperatures are given.

Book Description
The theory of absorption techniques, including line broadening and shifts, along with a brief description of the spectroscopy of the seed species Rb, will be given. A brief overview of the diode laser itself and the experimental setup for the technique follow. Results are split into two parts: preparatory and calibration work in a test cell and a small test shock tube, followed by results in HEG, are presented. Here time profiles for gas temperature T(trans) and velocity u are given for various HEG run conditions.
