• Chemisroption studies have been made in a closed system by a mass spectrometer operated statically. Nature of molybdenum surface was changed in a short duration. The total saturation coverage is 1.2_5x1O^14 molecules/cm^2 and is nearly equal to that for tungsten. A weekly bound adsorption state corresponding to the α-state of tungsten does not exist for molybdenum. Chemisorption states of two types are found; ζis 35% of the total saturation coverage and is a dissociative chemiisorption of which the heat of chemisorption is 2.7_5 eV. and εis 65% and a nondissociative chemisorption of 3.1eV. The average sticking probability is O.2 at low coverages. Generally, behaviours of molybdenum for nitrogen chemisorption are very resemble to that in the case of tungsten.
