The female group you're referring to is The Marvelettes. They released the hit song "Don't Mess with Bill" in 1966, which features a catchy Motown sound, but the song "Hypnotized" was performed by another Motown act, The Supremes. If you're looking for a specific song called "Hypnotized," it is actually by The Supremes, released in 1967.
