The spectral measurements of ammonia absorption lines from 6526 to 6538cm −1 have been performed at room temperature by using fiber-coupled distributed feedback (DFB) diode laser operating at 1.531μm. As many as 152 lines of ammonia and its line intensities, self-broadening and air-broadening coefficients were obtained, which include many weak lines not previously reported. The 20 strongest...
