Acetylene-filled pressure broadened short photonic microcells
We have developed short acetylene-filled photonic microcells (PMCs’) as optical frequency references in the near infrared region for applications in telecommunication, gas sensing, and metrology. The PMC is a 5-10 cm long hollow-core photonic crystal fiber (HC-PCF) in which the high pressure …

NMR studies of acetylene absorbed on supported platinum catalysts
… involving carbon-13, deuterons, and protons in acetylene (C2H2) adsorbed at room temperature on supported platinum catalysts. Measurements from 77""K to 158°K of the spin-lattice relaxation behavior of carbon-13 reveal multiple-exponential behavior. Calculations rule out an anisotropic T 1 as an …
