We discuss theoretical expectations for the {gamma}{gamma} partial widths of weakly-bound meson-meson ``molecule`` states such as the K{bar K} molecule candidates {line_integral}{sub o}(75) and a{sub o}(980). The theoretical consensus is that such states should have {gamma}{gamma} partial widths about an order of magnitude smaller than expectations for q{bar q} states with similar masses. This discriminating power implies that resonance production in {gamma}{gamma} collisions will be a useful experimental technique for identifying molecules. Experimental results for the {gamma}{gamma} partial widths of the {line_integral}{sub o}(975) and a{sub o}(980) support their identifications as molecules. Other possibilities for molecules, including the {line_integral}{sub o}(1720), are discussed.
