The NEMO-3 tracking detector is located in the Fréjus Underground Laboratory. It was designed to study double beta decay in a number of different isotopes. Presented here are the experimental half-life limits on the double beta decay process for the isotopes ¹⁰⁰Mo and ⁸²Se for different majoron emission modes and limits on the effective neutrino–majoron coupling constants. In particular, new limits on “ordinary” majoron (spectral index 1) decay of ¹⁰⁰Mo (T_1/2 > 2.7×10²² yr) and ⁸²Se (T_1/2 > 1.5×10²² yr) have been obtained. Corresponding bounds on the majoron–neutrino coupling constant are 〈g_ee〉 <(0.4–1.8)×10⁻⁴ and <(0.66–1.9)×10⁻⁴.
