The emission of O2 in the 1 Delta g band at 1.27 micron originating from the upper atmosphere of Venus is computed. Seven different production mechanisms are compared. The adopted value for the quenching rate coefficient is 3 x 10 to the -20th cu cm/sec. The results are compared with the measurements of Connes (1978) and it is shown that the values of the ozone profile calculated by Sze and McElroy (1975) are too low to explain the emission at 1.27 micron on the basis of the ozone photolysis. In this case, the ozone quantity would be underestimated by a factor of at least 10. The scarcity of kinetic data relative to the other processes, which involve ClO for example, does not allow a reliable identification of the main process responsible for the emission.
