| Popis | Laser induced fluorescence was used for detection of OH radicals in atmospheric pressure RF discharge ignited in argon in the so-called plasma pencil. Vibrational and rotational energy transfers in the excited states A 2 Sigma (v=0,1) together with appropriate life-times were studied. Since argon is relatively uneffective quencher, lifetimes of the excited states in plasma pencil are in the order of tens of nanoseconds, which is appreciably longer than the laser pulse. It was shown that the RET rate in plasma pencil is very high. Therefore, the rotational energy distribution of the excited state can be considered to be well thermalized. |
