What are some examples of internal rhyme?

so this a poem, where the internal rhyme is:-

Once upon a midnight dreary, while I pondered, weak and weary, Over many a quaint and curious volume of forgotten lore, While I nodded, nearly napping, suddenly there came a tapping, As of someone gently rapping, rapping at my chamber door. " 'Tis some visitor," I muttered, "tapping at my chamber door; Only this, and nothing more."

In this one excerpt, you can see internal rhyme:

Within one line with “napping” and “tapping” Internal rhyme between two lines with “napping” and “rapping” Internal rhyme between the last word of one line and a word in the middle of the following line with “tapping” and “rapping”
