  We present a list of weak emission lines (WELs) observed in a sharp-lined B3
V star {\iota} Her (HD 160762) using high resolution (R = 65000) and high SN
(~1300) spectral data. The list covers a spectral region between 4900A and
10000A. We register 207 WELs in this star and identified 190 lines including
ten ions (nine elements). Emission lines of C II, N I, Cr II, Mn II, and Ni II
have been identified among normal B-type stars for the first time. 17 emission
lines remain unidentified. We compare our list with the published list of WELs
for 3 Cen A (Wahlgren and Hubrig 2004) and found that numbers of detected
emission lines reflect differences in abundance between these two stars. We
detect 13 C I emission lines in iota Her (normal in C), while only one C I
emission line is found in 3 Cen A (deficient in C). Many emission lines of P II
and Cu II have been detected in 3 Cen A (overabundant in both P and Cu), while
no emission line of these ions has been found in {\iota} Her. Many emission
lines of Fe II are visible in the shorter wavelength side of 6000 A in iota
Her, while these emission lines are missing in 3 Cen A. Close inspections of
spectral data of 3 Cen A reveal that apparently missing Fe II lines appear as
absorption lines in this star. Because these two stars have nearly the same
atmospheric parameters (Teff and log g), a physical interpretation which is
independent on these two parameters is needed to account for this observation.
