Using our diode-laser- helium cluster machine setup we were able to detect the R(0.5) ²Π_1/2 transition of¹⁵N ¹⁸ O in heliumnanodroplets at 1796.38 cm^-1. The line is red-shifted by 1.55 cm^-1 with respect to the gas-phase. The transition and has a FWHM of 0.050 cm^-1, which agrees very well with the result for ¹⁴N ¹⁶ O , indicating rotational relaxation.
