Abstract

Measurements of the band heads and of the partially resolved rotational structure of the MgF absorption bands are used to evaluate the following constants for the

{}^{2}Σ

{}^{2}Σ

system:

ν_{00} = 37, 187.4

{cm}^{- 1}

{B_{0}}^{'} = 0.537

{B_{0}}^{''} = 0.518 \pm 0.010

{r_{0}}^{''} = 1.75 \times 10^{- 8}

cm and for the

{}^{2}Π

{}^{2}Σ

system:

ν_{00} = 27, 846.5

{B_{0}}^{'} = 0.529

{B_{0}}^{''} = 0.518

A = - 34.3 (or + 38.3)

. The isotope effect of Mg is observed in the +1 sequence of

{}^{2}Σ

{}^{2}Σ

bands. The BeF bands do not appear in absorption under similar conditions.
