Eigenfrequencies of two mutually interacting gas bubbles in an acoustic field are discussed theoretically and numerically. It is shown by a linear theory that a bubble interacting with a neighboring bubble has three eigenfrequencies that change with the distance between two bubbles, and the sign and magnitude of the primary Bjerknes force acting on bubbles also change according to the change in the eigenfrequencies.
