We describe the analytic continuation of the heat kernel on the Heisenberg group ℍn(ℝ). As a consequence, we show that the convolution kernel corresponding to the Schrödinger operater eisL is a smooth function on ℍn(ℝ) \ Ss, where Ss = {(0, 0, ±sk) ∈ ℍn(ℝ) : k = n, n + 2, n + 4,…}. At every point of Ss the convolution kernel of eisL has a singularity of Calderón–Zygmund type.
