Abstract
High resolution spectra of the $[14.6]^{2}\Delta_{5/2} - X^{2}\Delta_{5/2} (9.0)$ band of Nil near $16594 cm^{-1}$ have been observed under jet-cooled condition following the reaction of laser ablated nickel metal with $CH_{3}I$. With a line width of around 70 MHz, the hyperfine structure is partially resolved. Since the $^{58}$Ni atom has nuclear spin I = 0, the hyperfine structure arises from the iodine atom, which has a nuclear spin of 5/2. Both $^{2}\Delta_{5/2}$ states conform to case $a_{\beta}$ coupling scheme. Molecular constants for both the upper and lower $^{2}\Delta_{5/2}$ states will be reported.
