Abstract: | The arc emission spectrum of the ReO molecule has been photographed in the region 590–860 nm and three bands of a single electronic transition have been rotationally analyzed. The separation of lines of the isotopic molecules 185ReO and 187ReO leads to the conclusion that the vibrational assignments for these bands are 1-0, 0-0, and 0–1. It is conceivable that an electronic isotope shift of ~0.08 cm?1 exists. The following vibrational and rotational data (cm?1) have been determined: ν0(0-0) = 14 038.42, , ; B′e = 0.3889, α′e = 0.0019, B″e = 0.4257, α″e = 0.0043. It is concluded that Λ′ ? Λ″ = +1 with Λ″ ≥ 2. |
