      More Details Abstract Fulltext PDF

      Laser-induced breakdown spectrum has been recorded in the region of 380–455 nm using second harmonics of Nd:YAG laser, computer-controlled TRIAX 320 M monochromator with a reciprocal linear dispersion 2.64 nm/mm fitted with ICCD detector. The spectrum consists of 108 bands, which are classified into four new subsystems E0u+ (1Σu+) → A1g(3Πg), J0g±\1g(3Σg+) → D1u(1Πu), F1u → A0g±(3Πg) and F1u → A2g(3Πg) along with additional bands of the known system E0u+(1Σu+) → A0g±(3Πg). The molecular constants for these systems have also been determined.
