The English word 'excitation' is often too formal or technical for everyday emotional excitement. In Japanese, using 興奮 is natural, but directly translating 'excitation' as 励起 in non-technical contexts will sound odd. Stick to 興奮 or 刺激 for general excitement.
興奮 (こうふん) describes the state of being excited, while 刺激 (しげき) refers to the stimulus that causes excitement. For example, a thrilling movie is 刺激的 (しげきてき), and the feeling it gives you is 興奮 (こうふん).
彼女を見てムラムラした。
