Broadband Rotational Spectrum and Molecular Geometry of OC  AgI Nicholas R. Walker, Susanna L. Stephens, Anthony C. Legon 1 67 th International Symposium on Molecular Spectroscopy, Ohio State University, Engineering and Physical Sciences Research Council

Design of Laser Ablation Source for CP-FTMW Spectrometer Design Challenges Designs must consider; Need for the target to rotate, translate and switch direction in a vacuum. Geometry of source and location of laser. Need for daily and weekly disassembly and maintenance. Can we also have flexibility in selecting experimental conditions?

Laser ablation source informed by the designs currently used by Legon and co-workers, Duncan and co-workers, Gerry and co-workers, Ziurys and co-workers. Laser ablation source Rod holder

Power divider SPST switch Mixer Low noise amplifier Pin diode limiter Adjustable attenuator 300 W Power amplifier AWG ( GHz) Oscilloscope (0-12 GHz) 10 MHz reference frequency PDRO (19.00 GHz) GHz GHz 12.2 GHz Low-pass band filter CP-FTMW Spectrometer
