The Bohr-Sommerfeld (BS) rule for a spin system was investigated. The rule applies to both integer and half-integer spin. Tunneling effects were not incorporated into BS calculations. This rule is tested for various model, in particular, the Lipkin-Meshkov-Glick model, and found to agree well with exact results.
