The nominal Kepler mission provided very high-precision photometric data.Using these data, interesting phenomena such as spots, and ``hump and spike''features were observed in the light curves of some normal A and metallic linedA stars (Am stars). However, the connection between such phenomena and thechemical peculiarity of the Am stars is still unclear. In order to makeprogress on these issues, its important to collect high-resolutionspectroscopic data to determine their fundamental parameters and individualchemical abundances. In this paper, we present a spectroscopic study of asample of ``hump and spike'' stars in the nominal Kepler field. We used datacollected with the High Efficiency and Resolution Mercator \'{E}chelleSpectrograph (HERMES). We determined the spectral type of these stars andobtained the atmospheric stellar parameters such as effective temperatures,surface gravities, projected rotational, microturbulent and radial velocities.We also performed a detailed individual chemical abundance analysis for eachtarget. We confirmed KIC 3459226 and KIC 6266219 as Am stars, KIC 9349245 as amarginal Am star, while KIC 4567097, KIC 4818496, KIC 5524045, KIC 5650229, KIC7667560, and KIC 9272082 are non-Am stars. To estimate their evolutionaryphases, all the stars were placed in the Hertzsprung-Russell (HR) diagram.Based on their spectral classification and chemical abundance pattern, wereclassified KIC 6266219 (previously treated as chemically normal) as an Amstar (kA3hA7mF1) and KIC 9272082 (previously treated as Am) as non-Am.
