情感 (qínggǎn) refers to deep, complex emotions or feelings, often in a psychological or artistic context (e.g., a film's emotional depth). It is more abstract and nuanced than 感觉 (gǎnjué 'sensation, feeling'), which is broader and includes physical sensations; and it differs from 感情 (gǎnqíng), which emphasizes emotional bonds between people or sentimental attachment.
