We performed Al-27-NMR measurements for the CaBe2Ge2 type single crystalline LaPd2Al2 in the temperature range from 100 K to 5 K to investigate the origin of the structural phase transition. We found that the line profile of the Al-27-NMR spectrum does not change entirely on passing through the structural phase transition at T-st.

Meanwhile, the peak position of the central line slightly change (approximate to 30 ppm) below 70 K, suggesting the orbital shift changes below Tst. The present Al-27-NMR studies evidence that the local electronic state at Al site is hardly affected by the structural phase transition.
