We determine the slope of the power spectrum of the matter perturbations fromthe Tenerife observations of the cosmic background radiation temperatureanisotropies. We compute the projected radiation anisotropy power spectrummeasured by this experiment and study its dependence with respect to the slopeof the temperature anisotropy spectrum on the sky. We show that Tenerife aloneimplies the upper bound on the spectral index of $m \le 3$. Strongerconclusions can not be reached due to the small data set. The method proposedcan be applied to any small scale experiment. Sampling the same region of theskywith different window functions could probe the slope of the radiationanisotropy power spectrum at different scales and confirm the presence ofDoppler peaks.Comment: 10 pages with figures, Postscript, (accepted by ApJ
